Version: unspecified (using Devel) OS: Linux We need a blacklist for all the drivers that do not support the Lanczos filter properly. My idea is to have a kconf file with key being the vendor (e.g. Intel, Ati) and as value a list of driver versions. So the distributions could also update the blacklist by using kconf update scripts. I opened a new bug report as we have several issues which will be fixed by this blacklist, this includes: * inverted thumbnails * too bright thumbnails * performance problems Please set all new bug reports to these issues as duplicate as this one. Today unfortunately showed that we will receive many reports :-( Reproducible: Didn't try

Looks like these issues are hit by people with intel cards and even the latest release of the xorg driver does not work. Is anyone aware of the fact that intel developers are tackling this problem?
Searching the FDO bugtracker for 'ALL lanczos' doesn't reveal anything Intel related. Could someone with enough detail knowledge of this issue please file a bug at the FDO bugtracker? I'd love to have this fixed as soon as possible by the Intel devs as the user experience with this bug is really really poor - makes one want to revert to KDE 4.4 :(
> Searching the FDO bugtracker for 'ALL lanczos' doesn't reveal anything > Intel related. Of course you won't find anything with lanczos as that is just one of many possible uses which triggers the bug. You would have to search for shader or similar. > I'd love to have this fixed as soon as possible by the Intel devs as the > user experience with this bug is really really poor - makes one want to > revert to KDE 4.4 :( We won't ship 4.5 with a bug causing such damage. We will either implement a blacklist or disable the filter.
SVN commit 1146195 by graesslin: Support for adding a driver blacklist to be used in the lanczos filter and blur effect. It uses a new config group Blacklist in kwinrc with two subgroups for Lanczos and Blur. The key of each entry in the group referrences the vendor either using GL_VENDOR or GL_RENDERER, e.g. "Intel" in renderer for Intel based chips. The value of the entries is a stringlist containing exactly the renderer information. This way it is possible to blacklist several mesa driver versions which are buggy. The blacklist is currently empty and will be filled with a kconf update script (which could also be done by distributions). So all users who experience problems and are subscribed to the bugs receiving this message, please upload your glxinfo.

Created attachment 48605 [details] Output of glxinfo (Mobile Intel® GM45 Express Chipset) Does anyone know of a LiveCD containing 4.5 RC1? I have another computer with a Intel graphics controller where I could test whether this issue occurs there too.
The problem occurs for you for blur or taskbar thumbnails or both?

Created attachment 48609 [details] Output of glxinfo Output of glxinfo on my Acer Aspire 5720Z laptop with "Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03)" chipset. Present Windows is too bright, but blur seems to work ok.
> --- Comment #12 from Stefano <stavallo unina it> 2010-07-05 18:18:35 --- > Sorry, do you need the whole glxinfo output? No that is in fact sufficient. I only need vendor and renderer string and in case of Intel I will only use renderer, that is "Intel", to identify the vendor.
I can't get the blacklist working here on RC2. What's shown in the debugging output when starting kwin: kwin(28299) KWin::CompositingPrefs::detectDriverAndVersion: GL vendor is "Tungsten Graphics, Inc" kwin(28299) KWin::CompositingPrefs::detectDriverAndVersion: GL renderer is "Mesa DRI Mobile Intel® GM45 Express Chipset GEM 20100328 2010Q1 " kwin(28299) KWin::CompositingPrefs::detectDriverAndVersion: GL version is "2.1 Mesa 7.8.2" kwin(28299) KWin::CompositingPrefs::detectDriverAndVersion: Detected driver "intel" , version "20100328" So I'm using this blacklist in my kwinrc now: [Blacklist][Lanczos] INTEL=Mesa DRI Mobile Intel® GM45 Express Chipset GEM 20100328 2010Q1 Tungsten Graphics, Inc=Mesa DRI Mobile Intel® GM45 Express Chipset GEM 20100328 2010Q1 But neither using INTEL nor the actual GL_VENDOR as key seemed to work. Did anyone get it working?
Sorry the format of the blacklist has slightly changed. Please have a look at http://blog.martin-graesslin.com/blog/2010/07/blacklisting-drivers-for-some- kwin-effects/ Please also note that your driver has an additional whitespace at the end of the renderer string. This one is currently required, but won't be in the final release (if I find the time to change it).
I added: [Blacklist][Lanczos] intel=Mesa DRI Intel(R) 965GM GEM 20100328 2010Q1 :-:2.1 Mesa 7.8.2 to my kwinrc and now taskbar thumbnails are correctly shown, yay! BTW I discovered it is hard to live without the present windows effect for window switching!
Got the blacklisting finally working using these entry: [Blacklist][Lanczos] intel=Mesa DRI Mobile Intel® GM45 Express Chipset GEM 20100328 2010Q1 :-:2.1 Mesa 7.8.2 It does only work with the strange messed up character between 'Intel' and the ® sign! The thumbnails are now fine again, but the overall performance is still really bad. Were there any other changes between 4.4 and 4.5 which could affect performance that drastically?
(In reply to comment #18) > It does only work with the strange messed up character between 'Intel' and the ® sign! "®" is the UTF-8 representation of of latin-1 "®" a) what editor do you use b) what encoding does it use? (in doubt, check with kwrite/kate where you can easily change the encoding)
(In reply to comment #19) > "®" is the UTF-8 representation of of latin-1 "®" > a) what editor do you use > b) what encoding does it use? (in doubt, check with kwrite/kate where you can > easily change the encoding) I'm using a utf-8 system - no latin-1 involved at all. I'm getting the ® as a result of the output when starting kwin which produces this lines: kwin(8883) KWin::CompositingPrefs::detect: glx version is 1 . 2 kwin(8883) KWin::CompositingPrefs::detectDriverAndVersion: GL vendor is "Tungsten Graphics, Inc" kwin(8883) KWin::CompositingPrefs::detectDriverAndVersion: GL renderer is "Mesa DRI Mobile Intel® GM45 Express Chipset GEM 20100328 2010Q1 " kwin(8883) KWin::CompositingPrefs::detectDriverAndVersion: GL version is "2.1 Mesa 7.8.2" kwin(8883) KWin::CompositingPrefs::detectDriverAndVersion: Detected driver "intel" , version "20100328" The GL_RENDERER string isn't messed up at all in the output of glxinfo - I'm wondering whether probably kwin messes up the encoding here. So it actually has nothing to do with the encoding of my kwinrc file.
> The GL_RENDERER string isn't messed up at all in the output of glxinfo - > I'm wondering whether probably kwin messes up the encoding here. For the blacklist it doesn't matter. I will change to a contains() instead of equals(), so we can just check for e.g. "GM45 Express Chipset GEM 20100328". Intel is already part of the key, so not a problem, if it's missing.
@martin no idea where the driver info is read (for the blacklist), but might require QString::fromLocal8Bit(char*) instead of QString(char*)

this works for me [Blacklist][Lanczos] Advanced Micro Devices, Inc.=Mesa DRI R600 (RV770 9442) 20090101 TCL DRI2:-:2.0 Mesa 7.8.2
Created attachment 49397 [details] automated extraction of blacklist lines from gl(x)info You didnt describe how _exactly_ one should transform gl(x)info output to the blacklist lines, and frankly to someone without GL knowledge it takes a few tries. So feel free to use the attached script to do the job: glxinfo | ./blacklist.pl or glinfo | ./blacklist.pl (glxinfo is called glinfo by the mesa people)
I noticed that when I run glxinfo I don't get 'GL_VENDOR', 'GL_RENDERER', or 'GL_VERSION' keys. e.g. $ glxinfo -i | grep -i 'GL_VENDOR\|GL_RENDERER\|GL_VERSION' returns nothing. My complete output from glxinfo is in Comment #13. However, if I run glxheads I get the proper keys: GL_VERSION: 2.1 Mesa 7.7.1 GL_VENDOR: Tungsten Graphics, Inc GL_RENDERER: Mesa DRI Intel(R) 965GM GEM 20091221 2009Q4 This is the mesa-utils I have installed: mesa-utils 7.7.1-1ubuntu3 Miscellaneous Mesa GL utilities So if I run the script attached to Comment #29, and modify the regex to handle optional spaces before the keys, I get: [Blacklist][Lanczos] Tungsten Graphics, Inc=Mesa DRI Intel(R) 965GM GEM 20091221 2009Q4 :-:2.1 Mesa 7.7.1 [Blacklist][Blur] Tungsten Graphics, Inc=Mesa DRI Intel(R) 965GM GEM 20091221 2009Q4 :-:2.1 Mesa 7.7.1 Putting this in my kwinrc and restarting kwin solves the problem. Thank you so much guys.

I think I need a blacklist too. At least Plasma was behaving really jerky at times with high loads in X of above 60 or 70 recents. Combined with the Nepomuk / Virtuose desktop search process/cpu load storm it made my KDE desktop unusable for minutes. Plasma just didn't react to any click on a window title in the window bar or somewhere else for about a minute easily. martin@shambhala:~/KDE/KDE-4.5-Effekte> glxinfo | ./blacklist.pl Use of uninitialized value $vals{"GL_VENDOR"} in concatenation (.) or string at ./blacklist.pl line 11, <> chunk 1.

I also wonder about the vendor. glxinfo shows me "DRI R300 Project" so I used that, but the other entries had either ATI or Advanced Micro Devices. I strongly suggest, disabling those effects by default and mark them as *experimental* in the configuration module - with a hint that certain gfx drivers might not yet be ready for prime time. Then anyone who enables those knows the risk of doing it. I think this is better than to leave users that upgraded with a barely usable desktop.
This one seems to do the trick: martin@shambhala:~> head -13 ~/.kde/share/config/kwinrc [...] [Blacklist][Blur] [...] DRI R300 Project=DRI R300:-:7.8.2 [...] [Blacklist][Lanczos] [...] DRI R300 Project=DRI R300:-:7.8.2 [...] But I wonder whether its to generic. But when this is driver related instead of chip related it should be okay. I do not yet know whether I need both entries. Is there a way to disable each effect manually in the GUI? I good thing to have for KDE 4.6 would be an "blacklist" button for problematic effects somewhere in the configuration GUI. That would save the casual user from putting together some entries manually. But then ideally this would all just work out of the box, so when enough blacklists entries are collected and bugs are reported upstream, this should work out eventually. I am willing to report upstream, but I need some details. If nothing helps, I can just report that these or that filter does not work with ATI Radeon DRI R300 driver yet and cross link bug reports.
Please add to the blacklist: OpenGL vendor string: Tungsten Graphics, Inc OpenGL renderer string: Mesa DRI Intel(R) Ironlake Mobile GEM 20100328 2010Q1 OpenGL version string: 2.1 Mesa 7.8.2
Please do not reopen this bug report. The initial need is implemented - that is the infrastructure for the blacklist. Updates to the blacklist might be added in future KDE releases and/or by distributions. Btw the card from comment #46 is already blacklisted.

I have some flickering using the desktop grid on my Intel X3100 (965?). Blur is disabled, but I tried to blacklist the Lanczos filter using: Tungsten Graphics, Inc=Mesa DRI Intel(R) Q35 GEM 20100328 2010Q1:-:1.4 Mesa 7.8.3 Re-launching kwin --replace, I see in the terminal "kwin(32004) KWin::LanczosFilter::init: Lanczos Filter disabled by driver blacklist". I still see some flicker, but less though.

Hmmm, strangely enough it seems I do not need any of these entries anymore - I removed them some time ago and all is well -, but version of MESA is the same: martin@shambhala:~> glxinfo | grep -i opengl OpenGL vendor string: DRI R300 Project OpenGL renderer string: Mesa DRI R300 (RV350 4E50) 20090101 x86/MMX/SSE2 TCL DRI2 OpenGL version string: 1.5 Mesa 7.8.2 OpenGL extensions: Well I upgraded Linux Kernel to: martin@shambhala:~> cat /proc/version Linux version 2.6.36-tp42-gtt-vram-apart-v2-dirty (martin@shambhala) (gcc version 4.4.5 (Debian 4.4.5-4) ) #1 PREEMPT Thu Oct 21 12:10:49 CEST 2010 This is vanilla with special fix from: [Bug 28402] random radeon/kms/drm related freezes with kernel 2.6.34 https://bugs.freedesktop.org/show_bug.cgi?id=28402

Because I was going to fill in a regression, kde 4.5 compoziting+effects ok, in 4.6b1 the effects are really slow (they get disabled automatically and desktop is fine then). 2.6.36.1 kernel, xf86-video-intel 2.13.0-4 driver same settings in kde 4.5 work fine. (without effects, kde 4.6 is considerably faster than 4.5, great job! :) ) btw, shall I file a new bug for 4.6 or can we add to this one?
neither, nor. either the slowness is unrelated to this item (you'll then have to figure whether maybe some effect causes this, try blurring, and file a bug on it) or you have to set the scale method to "smooth" rather than "accurate" (which is the lanczos filter, TLF has been removed for triggering crashes on at least at chips and not being a real advance anyway) the lanczos filter (only used during some scaling effects like present windows) uses some caching now and thus should be "fast enough" (and apparently is on ati & nvidia chips) but if it's still just too slow on a majority of intel chips, we may have to rethink the (unconditional) default setting.

Hi, With the latest 7.9.2 stable update of Mesa, the developers dropped some identifier strings from the DRI driver which causes the i965 driver to segfault the X server every time a window thumbnail is generated either through Alt+Tab or the panel hover effect: http://cgit.freedesktop.org/mesa/mesa/commit/?h=7.9&id=dfae3ffa0f5290d2ee1dcadbd6c125de468f032f Reverting the commit in Mesa fixes the problem but I think this should be handled in KDE/Kwin?
Sorry, we do not workaround driver regressions of outdated drivers. And we cannot workaround as 4.5 is already EOL and 4.6 should only be used with mesa 7.10 or later.
Plus in 4.6 can you just select the filter, no need for a blacklist (and lanczos is meanwhile by default off for intel chips?)
