Snapshot of the screen from my camera

Hello,

I've had this bug for a long time now and I finally decided to report this bug
today.

There seem to have a transfer issue between the graphic ram and the computer's
ram (vram <--> gtt ?).

The problem usually appears on small pixmaps (download from screen ?), never
bigger than about 200*200.

But, it also occurs when doing screen captures. That's why I made a picture of
small pixmap corruption with my camera and also added the same picture, but
using a screenshot.

$ lspci|grep VGA                                                                
01:00.0 VGA compatible controller: nVidia Corporation Quadro NVS 140M (rev a1)

$ dmesg
Nothing interesting there. If it is a transfer issue, we won't see anything
there, right ?

Keep up the good work,

Martin
