            Bug ID: 102962
           Summary: GPU crash running Overwatch in wine-staging
           Product: Mesa
           Version: 17.2
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel at lists.freedesktop.org

Running Overwatch in wine-staging 2.17 or 2.16 causes frequent GPU crashes, in
particular almost always when selecting Symmetra in the Hero Selection screen.
As far as I can tell there is no version of wine-staging (including specific
commits) that avoid this issue.

Interestingly, a patched version of wine-staging 2.16 and earlier
(https://github.com/gamax92/wine-overwatch) does not seem to trigger this at
all. (I suspect their removal of some wined3d related patches started to
trigger this, whilst the earlier version avoided it.)

No errors are shown on both wine's and mesa's end, although I have not
successfully tried a build with -DDEBUG CFLAG, which I could try in case this
is helpful.

I have tried working out which of the patches applied by the repository are
avoiding the issue, but haven't work out any good leads.

Running on Arch Linux with linux 4.13.3 (Custom compiled with unrelated
patches) and mesa 17.2.1. The issue can be reproduced both with the standard
wine-staging package on Arch as well as compiling the mentioned patched
version.

It might be worthwile to contact the wine developers about this, but their bug
reporting guidelines specifically say to not report driver issues there, so I
decided to report here first.
