           Summary: Issue with fullscreen games when DRI3 enabled
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW

          Priority: medium

I'm expecting issue with some 3d games with DRI3 enabled. Issue looks like some
frames are showing out of order. Issue reproducable with some games (Papa & Yo,
Dungeon Defenders, Amnesia) launched in fullscreen.
Video of issue - https://youtu.be/KivU8kEmhPc (video was captured on phone
because once I enable screencast recording issue disapear)
I tested on Ubuntu GNOME 16.04 x64 with Mesa 11.1.2 and latest mesa from git.
