https://bugs.freedesktop.org/show_bug.cgi?id=64695
Priority: medium Bug ID: 64695 Assignee: dri-devel@lists.freedesktop.org Summary: Enabling both MLAA and MLAA color 2D crashes Gnome Shell on Cayman (6950) Severity: major Classification: Unclassified OS: All Reporter: alexandre.f.demers@gmail.com Hardware: Other Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa
Forcing MLAA through driconf on Cayman 6950 crashes Gnome Shell if both mlaa and mlaa color (2D) are set (tested with both set to 8). If one of them is not set, Gnome Shell doesn't crashes.
MLAA color (2D) seems to have an effect on my Gnome Shell display. Tested with mesa's commit 7e17e72cb716c56264d4778684f6f23de69a56a1.

--- Comment #2 from Alexandre Demers alexandre.f.demers@gmail.com --- Sorry, I just had time to copy what I had reported in bug 56534. Gnome Shell ends up with a "Oops". I'll dig in logs to search for more clues.

--- Comment #6 from Alexandre Demers alexandre.f.demers@gmail.com --- Quickly tested with today's git and it still does the same "Oops". However, KDE doesn't have any problem to load. I'll give more info soon, I just don't have much time right now.
