           Summary: Heavy slow down X with Qt
           Product: Wine
           Version: 1.4-rc6
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

Hello, when I compil Qt or Qt program with wine, X use ~15% of my cpu, and have
like 1s with normal activie 1s where all freeze (mouse, X at 100%, ...)
No problem with other application like game, or 2D application.

To reproduct it:
Install the Qt SDK. Compil a big application (in my case
http://files.first-world.info/ultracopier/0.3.0.3/ultracopier-src-0.3.0.3.ta...),
and see the cpu, move the mouse, ... it's easy to see, all freeze at fixed
interval.
I'm with the open source drivers for my ati radeon. 1 year ago I problem don't
exists.
