            Bug ID: 94611
           Summary: Steam client hangs with Radeon DDX + DRI3
           Product: xorg
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
          Assignee: xorg-driver-ati at lists.x.org

I've managed to find out that it's not Steam's issue: with Radeon DDX with DRI3
enabled there's a *random* hang in Steam client, leaving the only option -
"kill -9". You can find the original issue on GitHub with the video attached
(showing the process of making the client "dead") here:
https://github.com/ValveSoftware/steam-for-linux/issues/4357
Right now I'm on Modesetting driver and everything seems to work fine. Either
it's the issue of a recent 1.18.4 X.org update, either it's a regression in
DRI3 code. I'm thinking of the former, because everything was fine a while ago.
