Problems with scrolling using DVI output on GF5200

[bartoszr]

Hi everyone,

I have recently swithced over from using the D-SUB cable to DVI while using my DFP and my GeForce FX5200. The problem occurs ONLY when using DVI and nvidia driver (I tried nv drvier to compare results, the bug does not reproduce with nv, so it is not a cable or DFP failure) and from what I see is reproducible and occurs under heavy CPU load (I achieve this by using Eric, the Python IDE :-)). Anyhow, the trouble is that when I'm scrolling a window in Eric, throughout the screen I can notice several horizontal lines, that look like they're not drawn corrently (strange colours). From time to time the screen also goes blank for about 1 second or so. Then it goes back to normal. Until I scroll the window again ;-). Can anyone help? I attach the log file as asked.
