Bugreport: glitches / artifacts with 180.x (now 180.44) + kde4 when windows are moved

[radoeka]

[I have sent the information below to the email address that is displayed when running nvidia-bug-report.sh, that was almost a week ago. Sofar no response]

Hopefully this is the right place to get support for the problem I see with my graphical system of which nvidia is the main part.

I see artifacts / glitches when a window moves from the back to front (top) or the other way around. When I move the window on top a little bit, the artifact / glitch disappears. The artifact also disappears if a mouse comes close to the artifact. In the attachments you can see the problem that I have.

I assume that all information about the video system is in the nvidia-bug-report logfile. some relevant information:
GeForce 7600GT, AGP 8x, driver 180.44

I'm using it in combination with kde-4.2.2. However, I saw the problem also with earlier kde releases (4.1.x). I have used nvidia-drivers 180.22 and later and on all those releases the problem exists.

glxgears reports around 2000 FPS, which looks good to me. At least the card works fine (except for the artifacts / glitches).

The InitialPixmapPlacement value = 1, but changing this to 2 does not seem to help. The cache is on and its size is PixmapCacheRoundSizeKB.

I have this problem with an 8800GT. It happened with KDE 4.2.1, 4.2.2, and all 180.* or 185.* series drivers. The "dim screen for administrator mode" desktop effect really seems to trigger it... I get artifacts all over the screen if I use kdesu. I see it a little bit in yakuake too.

I'm running Slackware-current with kernel 2.6.29.1.

Where can this setting be found in kde system settings?

I'm seeing this problem as well on my setup.

Kde 4.2.2 + nvidia 180.44 @ GeForce 8500 GT 512MB

Arch Linux 32bit kernel 2.6.29

I've moved to Arch Linux 64bit and the problem has gone away, this is possibly only a problem with the 32bit nvidia driver.

Last week I upgraded to nvidia-180.51, but the problem is still there

Nvidia, please provide a fix for this, as a desktop with such lines is disturbing to work with!

I get this problem too with the last several drivers I've tried:

Qt: 4.5.0
KDE: 4.2.2 (KDE 4.2.2)
OpenGL renderer string: GeForce GTX 280M/PCI/SSE2
OpenGL version string: 3.0.0 NVIDIA 185.18.14
Mandriva Linux 2.6.29.3-desktop-1mnb #1 SMP x86_64 Intel(R) Core(TM)2 Quad CPU Q9000 @ 2.00GHz

185.18.14 seems to be better but I've still seen it a few times.
