When scrolling left or right, many pixelgroups don't change, resulting in fractals and weird looking picture-parts. Scrolling up and down is working great.

I tried this on 2 computers, both with linux (up to date systems running: debian testing, ubuntu natty). Unfortunately both have an ati graphic card, so it might be a fglrx problem. Maybe someone knows a solution or can tell me if it's a problem for any linux users or just for those who have an ati card.

I already tried different settings in the xorg.conf, like activating horizonal sync and so on, but no effect.

Catalyst Control Center (amdcccle) has a setting like "Tear Free" - but this doesn't eliminate this error, it just seems to reduce it.

Thanks for any help - even if it's just help like finding out if it's a driver/card/gtk/gimp/... problem.!

Could you show what's in /var/log/Xorg.log (after scrolling horizontally). I've never used ATI cards because of the poor drivers. Gerard.

There seems to be no change in log..

Thanks for reply!

Another logfile that may contain info is /home//.xsession.errors.

I think that should be .xsession-errors

http://pastebin.com/20zMEL6Y - This is my .xsession-errors by running gimp and producing the error. Nothing useful in there I guess... I could also paste the .xsession-errors from before running gimp, but it's very very long...

I'm pretty sure that it's a driver problem, because there was once a combination of fglrx driver and gimp version that did not have this issue. Only problem is that I don't know if it is gimp or fglrx which produces this error... But I cannot see this problem in any other program, so I guess it might be a combination of both? (Or a GTK + fglrx error..)
