Version: svn trunk (using 4.1.70 (KDE 4.1.70 (KDE 4.2 >= 20081016)), compiled sources) Compiler: gcc OS: Linux (i686) release 2.6.27-zen1 I can't understand why the font looks like that. Maybe it should pickup settings from plasma theme or it should be configurable in the plugin itself. The look of the font right now is just ugly in my opinion. See the screenshot.
Created attachment 27993 [details] Shows the font
Which graphics driver are you using? Have you seen this happen to any other, non-KWin fonts?
Its happening on fglrx and nvidia, I have never seen this font in any other application I think.
Go into system settings -> appearance -> fonts. What is your "general" font set to? Are you using anti-aliasing or a different DPI settings? Does the glitching still occur when set to something else (Try a few)?
General is: Bitstream Vera Sans Regular 8. I'm using a dpi of 90. Is this feature using the general font? I don't think so, because the font looks much bigger. However when I change the size it changes as well, but still looks ugly. I'm still investigating.
I just remembered that I'm using patched font system: http://forums.gentoo.org/viewtopic-t-511382-postdays-0-postorder-asc-start-0.html But as far as I know these patches are in kubuntu as well, so.... Whats different for this font in kwin than all others? Becaus I have this ugly font there only...
Can you confirm that removing the patch fixes the problem?
I have disabled the patches, recompiled the affected patches, restarted kde but I'm still having the ugly font.
I have this problem to on my intel card, since kde 4.0. I have it in kde from kubuntu, opensuse and from a self-compiled kde 4.7.73... it's connected with sub pixel hinting: disabling it from system settings makes the fonts look ok.
I can now reproduce.
