Summary: [855gm] gnome-shell misrendered Product: Mesa Version: git Platform: Other OS/Version: All Status: NEW Severity: major Priority: medium Component: Drivers/DRI/i830 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: chris@chris-wilson.co.uk
Created an attachment (id=48644) --> (https://bugs.freedesktop.org/attachment.cgi?id=48644) screenshot
A couple of immediately apparent issues:
1. The top-panel bar is absent.
2. Window shadows are white rather than black (or at least I presume they're meant to be shadows and not a glow!)

--- Comment #1 from Eugeni Dodonov eugeni@dodonov.net 2011-09-08 15:55:50 PDT --- This issue is affecting a hardware component which is not being actively worked on anymore.
Moving the assignee to the dri-devel list as contact, to give this issue a better coverage.

--- Comment #2 from Eric Anholt eric@anholt.net 2012-03-02 17:32:51 PST --- The first issue is fixed:
commit 7d13a6e64bf88566875a8f68e0aac9b937e30feb Author: Alban Browaeys prahal@yahoo.com 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. [change by anholt]
