             Bug #: 53130
           Summary: 99c65ba breaks rendering (flickery, eventual fail)
    Classification: Unclassified
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: bugspam at moreofthesa.me.uk


I noticed broken rendering in mesa git fairly recently.

In Unvanquished (current release), the effect with its GL3 renderer is that the
display becomes more and more flickery, and eventually rendering apparently
ceases; the game remains otherwise responsive. Its GL ('vanilla' renderer, much
as in Tremulous) is unaffected.

Bisection points at the following commit; I've confirmed locally that git
master with this reverted does not exhibit the broken behaviour.
