            Bug ID: 109732
           Summary: DiRT Rally has extreme graphical corruption and
                    performance loss
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal

It was observed extreme graphical corruption on DiRT Rally when using Iris. The
elements on screen have trouble to disappear, creating more and more artifacts
as the game is played. It was also observed a 40 FPS loss.

Below are the images showing it using Iris and using i965:

I understand Iris was just added to the main Mesa repository, thank you for the
effort. I'm reporting this to make you aware of its behavior on DiRT Rally.
