Bug #: 29371
           Summary: Support GNOME Mutter's new suspended compositing for
                    fullscreen apps
           Product: Wine
           Version: unspecified
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

Mutter 3.2 supports suspended composition for apps that requests it. Wine
doesn't seem to request / fall into the heuristics.

I'm currently playing some DOOM 3 and it's clearly not undirected when playing
from GNOME Shell. Fallback mode has better performance as nothing is
composited.

If an app is fullscreen it should suspend composition.

Yes I did that back then when I decided on that heuristics, even "benchmark
only" stuff like unengine heaven does that.

They missed Wine games.
