Version: (using KDE 4.2.0) OS: Linux Installed from: Ubuntu Packages When using firefox in fullscreen (F11) or other apps, like video (mplayer, vlc, etc) in fullscreen, there are many small quirks (a combobox or menu that opens up causes the screen to flicker other images. CTRL-F* to go to another desktop will show that desktop grey. Eventually, a kwin or plasma crash occurs (probably after CTRL-TAB) Should be quite easy to reproduce, just run appps in fullscreen
It may be related to your configuration / graphics card& drivers If you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? Thanks :)
The reporter sent me an email: ---------- I'll read it and see what I can do for you. Meanwhile, if it helps, I have a Dell latitude D629 laptop, lspci gives this for VGA card: 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03) 00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03) Using the i915 driver that is included in the kernel. Let me read the report and I'll get back to you
.. and this is with desktop effects on, i'll wager? this isn't a plasma issue, in any case; it's a window manager issue at best, and likely an x.org problem. plasma doesn't do anything with windows! moving to kwin to let them decide what to do with it.
This is caused by the automatic unredirection of fullscreen windows. You can disable this by adding "UnredirectFullscreen=False" into your ~/.kde4/share/config/kwinrc file. Using this workaround may cause other bugs though so if you do this and report another bug to us please mention that you have made this change in your description.
