Hi,
since I've upgraded from F10 to F11, I'm getting corrupted graphics in many kde apps. See
http://iktp.tu-dresden.de/~petzold/corrupt.png
for an example. Usually, the desktop background is displayed in toolbars instead of the regular toolbar background, but sometimes this also happens in other places. If I resize the window or mouse-over the affected parts of the window, the problem fixes itself, but it will reappear soon. I've only seen this with kde apps and not with others like firefox. Since F10 and F11 use the same qt version I suspect the intel drivel for my venerable i830 graphics chipset is at fault. Does anybody on this list use F11 with kde on a machine with an (old) intel chipset with or without the same problems that I'm seeing? I haven't had the time to play around with any of the different acceleration options of the new intel driver, I'll check that later.
Cheers,
Andreas

Under F11 Intel chipsets use Kernel Modesetting by default. This can cause some problems in some configurations (I'm far from being an expert). It's easy to check, just reboot with "nomodeset" added to the Grub kernel line.

It's odds-on that acceleration method is the key. Intel and ATi are both rapidly developing their drivers to meet the more stringent requirements of recent distros. Kde4 desktops in particular uses parts of the driver not stressed in older versions. On this laptop I have an ATi display. The desktop works best with AccelMode set to EXA, but kuickshow has corrupted display in EXA and looks fine with XAA. It really does seem to be something where you just have to experiment.

since I've switched AccelMode to XAA on my latop with the old i830 chipset, I didn't see any graphics corruption. I don't use desktop effects on this machine anyway, so I'm not missing out on any bling features :-)

Best would be to report those problem at https://bugs.freedesktop.org/ and let the intel developers know your exact hardware.
Since F10 and F11 use the same qt version I suspect the intel drivel for my venerable i830 graphics chipset is at fault.
Most likely, intel didn't care a lot for chips <i945.

Hi, I'm facing the same problem with nouveau driver but I'm not sure if it is driver problem or kde problem. I can't reproduce this at will. With nouveau this occurs much often than with nv driver, at least it seems to me. I usually get some messages in ~/.xsession-errors: QPainter::begin: Widget painting can only begin as a result of a paintEvent QPainter::translate: Painter not active QPainter::setClipRect: Painter not active QPainter::hasClipping: Painter not active QPainter::setPen: Painter not active QPainter::setBrush: Painter not active QPainter::drawRects: Painter not active QPainter::hasClipping: Painter not active QPainter::setPen: Painter not active QPainter::setBrush: Painter not active QPainter::drawRects: Painter not active QPainter::hasClipping: Painter not active

I've seen this on the 945 chipset, and I've seen total corruption of the screen.. This is on a Asus EEEpc 1000he.
