https://bugs.freedesktop.org/show_bug.cgi?id=38873 --- Comment #2 from Eric Anholt <eric@xxxxxxxxxx> 2012-03-02 17:32:51 PST --- The first issue is fixed: commit 7d13a6e64bf88566875a8f68e0aac9b937e30feb Author: Alban Browaeys <prahal@xxxxxxxxx> Date: Thu Feb 2 19:20:22 2012 +0100 dri/i915: Fix off-by-one in i830 clip region size. The hardware, like i915, uses an inclusive bounds on min and max for the drawing rectangle, but we were providing a number for exclusive. The number of bits used by the hardware only covers this value going up to the maximum size, so when we programmed 2048 as the maximum inclusive X, it saw a maximum X of 0 and clipped all rendering. This caused rendering failures in gnome-shell. Fixes piglit fbo-maxsize. v2: dropped changes to the blitter, which does use an exclusive x2, y2.
