--- Comment #25 from Jean-Noel Rivasseau elvanor2007@gmail.com 2011-01-26 06:58:39 CST --- Thanks a lot for your work, Roman! I implemented your workaround in KDE 4.4 and now it works perfectly. Before that I had to click many times on the Fullscreen button in KDE to restore it...
And as Alexandre says, it would be nice to find the root cause of the bug so this can be fixed in Wine (eg without the KDE workaround).
