In reply to Meino Christian Cramer (mccramer@s.netic.de):

Hi Meino,

Not to complain or anything.  I think your assumptions are a little bit
faulty though.  More than likely this is a video card problem.
(Thats not to say that it might not be something in blender 
that is tickling it...  But if it were a blender specific thing
everyone running Linux would be having frequent lockups...)

3d graphics programs just tend to use the graphics cards special
features  a lot more than standard apps so thats more than likely why
you only see the problem in blender.  Even the gimp (a huge program)
mostly just uses standard 2d operations and you probably will not
notice anything.

Lots of times this sort of thing is something like a register doesn't
get cleared and then is read as garbage later on or something...
Its unpredictable and in general there isn't a do this step by step
to reproduce the problem.  Thats why as someone else stated its pretty
hard to debug, and or tell when the problem is actually fixed...

Kent
