** Description changed:
Binary package hint: libgl1-mesa-dri
I upgraded xorg-edgers packages on 2009-08-29 16:16 MEST.
This changed among others this package:
libgl1-mesa-dri (7.6.0~git20090825.87f83e19-0ubuntu0tormod) to
7.6.0~git20090829.00413d87-0ubuntu0tormod2.
A downgrade of all the xorg-edgers ppa packages and subsequent package by
package upgrade along with digging in the history of synaptics ascertained that
it is this particular upgrade of libgl1-mesa-dri that caused screen corruption
in blender as shown in the attached video. Along with that Extreme Tux Racer
lost half its performance.
The above is an edit/complete rewrite of the original bug report. My
comments in the comment section below show what led to this rewrite. The
rest here below is original.
Please let me know if you need further information or testing to resolve
this regression.
