Created attachment 61970 [details] example of a corrupted menu Version: 4.6 (using KDE 4.6.3) OS: Linux When using Intel HD Graphics 3000 (Sandy Bridge), some of the menus were corrupted (see the attached image). For example the window settings menu, displayed after Alt+F3 or the right-click menus were corrupted like this. Enabling or disabling desktop effects does not solve the problem, the only difference is that with effects enabled the black areas are transparent. Not sure if it's a driver or KDE problem - I'm using the xf86-video-intel-2.14.0 driver and 2.6.38 (gentoo-r6) kernel. Adding "export QT_GRAPHICSSYSTEM=raster" to the .kde4/env/qt-graphicssystem.sh script solved most of the issues, although not all of them. After changing style from "oxygen" to "plastique" everything works fine. Reproducible: Always Steps to Reproduce: Remove the QT_GRAPHICSSYSTEM and/or set the style to oxygen again. After restarting KDE, the menus are corrupted again. Actual Results: corrupted menus :-( Expected Results: not corrupted menus ;-) Most of the information came from this thread http://forum.kde.org/viewtopic.php?f=15&t=96031
can't reproduce. Must be issue with driver indeed (especially since it works better with different graphics system, and without any other change in oxygen.) So nothing I can do about it ... Here, I'm using: x11-driver-video-intel-2.15.0, but also with different graphics card. So that does not prove anything. I'd suggest to try upgrade (or downgrade) intel driver though.
I've tried to downgrade to x11-drivers/xf86-video-intel-2.14.0, but it behaves exactly as x11-drivers/xf86-video-intel-2.15.0-r1.
The same glitches here with nvidia cards: http://forums.gentoo.org/viewtopic-p-6778976.html http://users.telenet.be/patrick_allaert/tmp/garbled.ogv
Small note regarding Sebastian's comment: this isn't a pure nvidia environment as he may have suggested but a nvidia card with optimus technology aside of an intel card: $ sudo lspci -v | grep -i vga 00:02.0 VGA compatible controller: Intel Corporation Device 0116 (rev 09) (prog-if 00 [VGA controller]) 01:00.0 VGA compatible controller: nVidia Corporation Device 0df4 (rev a1) (prog-if 00 [VGA controller])
The oxygen style for gtk and tooltips are corrupted too. The culprit on my system seems to be xorg-server. Downgrading it from 1.10.2 to 1.9.5 fixes all issues.
I see this in radeon, as well. Only with oxygen. Changing to anything else seems to fix it. Right now using qtcurve.
Still valid with latest drivers and latest KDE (KDE 4.8) ?
(In reply to comment #7) > Still valid with latest drivers and latest KDE (KDE 4.8) ? Seems to be fixed on my machine (I'm using KDE 4.8.1 and xf86-video-intel-2.17.0-r3).
I didn't even remember this. I don't at which point this was solved, but I haven't noticed it for a long time.
ok. I guess we can safely close then. Please reopen if problem reappears.
I still get this in 2014, also using an Intel HD 4600 video controller. The corruption always appears in the System Activity window (when pressing Ctrl+Esc), and also on the background of KSnapshot and its child windows (such is the Save Dialog)

Nevermind, seems it was a video driver issue. Upgrading to a git version fixed the corruption.
