            Bug ID: 93594
           Summary: Flickering Shadows in The Talos Principle
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: haagch at frickel.club
        QA Contact: dri-devel at lists.freedesktop.org

I haven't seen specifically this bug mentioned here yet. Apparently this has
been an issue for some time and with latest mesa git and llvm svn 256490 it
still happens.

Video demonstrating the flickering (ignore the long pause):

My hardware:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Wimbledon XT [Radeon HD 7970M] (rev ff)

Here is a trace (657MB uncompressed, 409MB compressed):
http://haagch.frickel.club/files/talos.trace.xz

Replaying the trace on radeonsi shows flickering shadows.

When replaying the trace on intel, the shadows don't seem to flicker.
