Hi,

Just moved to xbmc (which uses gl), from freevo and more often than not, I get
extreme diagonal rendering artifacts on the gui. Pretty much each gui object (a
box, a single character, etc) has a diagonal split and either of the halves
renders o, and the other is mostly black. The diagonal flickers between the
corners at a rapid pase (~ 4 changes / second).

I files report on it at xbmc (http://trac.xbmc.org/ticket/14017) which also has
screenshots and a short movie grab attached.

Freevo worked ok, so I guess this is somehow related to new code paths executed
by xbmc (both 11.0 and 12-git suffers). I have no idea if it's kernel driver
related or somewhere higher in the stack.

Ideas to narrow this down appreciated. xbmc is the only app which behaves like
this.
