Description Chris Rankin 2013-09-30 21:39:38 UTC 
This commit is causing a patchy line of tiny little squares across one of the main diagonals on the screen (bottom-left to top-right):

68f6dec32ed5eede361f76c8dbdf897652659baf is the first bad commit

screenshot attempting to show problem

The corruption is of a flickering nature, which has made it difficult to capture. But you can hopefully see at least two little black squares which are definitely not supposed to be there.

This is with a HD4890 (RV790).
Comment 3 Jos van Wolput 2013-10-01 01:42:22 UTC 
Startng icedove/firefox with
OpenGL renderer string: Gallium 0.4 on AMD RS780
OpenGL version string: 2.1 Mesa 9.3.0-devel
commit mesa-68f6dec32ed5eede361f76c8dbdf897652659baf (bisected)
is causing a completely corrupted screen and xorg errors,
making mesa unusable.

This should be read 'Startng iceweasel' (Debian's Firefox), not icedove (Debian's Thunderbird).

Have you tried a clean build, i.e. after at least make clean?

When I bisected this, I was performing "make distclean" each time.

Yes, I did make clean to get a clean build.

This issue is now fixed for me, presumably by:

commit b893bbf438e1924d5f47370b29421642e79b0221
Author: Marek Olšák <marek.olsak@amd.com>
Date:   Thu Oct 3 16:39:50 2013 +0200

    r600g,radeonsi: create aux_context last
    
    This fixes a regression caused by 68f6dec32ed5eede361f76c8dbdf897652659baf.
