--8<---------------cut here---------------start------------->8---
08:00.0 VGA compatible controller: NVIDIA Corporation G84 [GeForce 8600 GT] (rev a1)

in it.
I have feeling that graphic drivers have bug, but I am not sure:
My simple test:
ebook-viewer anthing.epub
after some page changes I got:

The same actions on laptops wiht intel graphics are successful.
Any hints if this a bug in xserver-xorg-video-nouveau libdrm-nouveau2 or
kernel driver?
