           Summary: StarCraft2 screen garbled as "bad glass" on ATI cards,
                    when not using orm=backbuffer
           Product: Wine
           Version: 1.3.0
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: NightNord at gmail.com


With any OffscreenRenderingMode other than backbuffer, game screen (both in
menu and missions) is garbled as shown on photo. There is few moments about
this garbling:

1) It happens only if SC2 rendering size is the same as you monitor resolution.
I.e. if you are playing fullscreen OR using virtual desktop with same size,
dispite of virtual desktop's window state.
2) It could be reverted by switching resolution or windowing mode in-game. But
it will return when;
a) You are entering settings, from menu or from in-game, doesn't matter.
b) On loading screen, at ~90% of load.

Common surrounding of reappearing of the bug is that at this moment screen
flickers once.

When you are using orm=backbuffer, but also appears at noted actions for a few
seconds, but then screen reverting back to normal.

Photo attached are done with settings:
orm=fbo
videomemorysize=512 (unrelated)
UseGLSL=disabled (unrelated, but fixes another bug)

This is not only wine related, as same bug could be encountered in native games
and screen isn't cleared on SC2 exit until you will (blindly) execute something
like xrandr -s 1,

I'm making photo of this bug, as I've failed to make screenshot - i'm getting
black image every time with any tool. Also note, that only right part of screen
is heavily garbled, while left part is mostly clear, and this is as it always
is.
