Help tracking down glitch in redraw for XFCE

[halpo]

I'm using XFCE and recently there turned up a redraw issue. Occasionally, and apparently at random the screen redraws incompletely. Windows disappear as well as the panels. when I mouse over a window and it changes that portion will redraw correctly.

I've not found any solution to this through Google. I have combed through my logs repeatedly without seeing anything that might be related to something triggering this behavior. It does seem to happen more often when running more intense applications such as thunderbird, chrome with video, and a remote desktop through Citrix Receiver. I'm sorry it is repetitive but not reproducible.

I'm at a loss of where to look to fix this. Please help.

I'm running:
Kernel: linux-3.16.2
Nouveau graphics driver
Intel i7 970
nVidia GTX480

make sure you have latest xf86-video-nouveau

which includes

this ensures sync of bufferswaps to vblank and a doubled framerate == smoother operation (this was very noticable with kwin & compositing)



are you using compositing with xfwm4 ? if not enable it whether that helps

you could also switch compositors and see whether that changes things (kwin, xfwm4, compiz; fusion-icon is very useful in this regard)
