--- Comment #7 from Graham Inggs graham@nerve.org.za 2012-04-30 03:54:18 CDT --- Still occurs with Angry Birds Seasons 2.3.0 in Wine 1.5.3 on Ubuntu 12.04 x86_64.
If the file 'Program Files/Rovio/Angry Birds Seasons/config.lua' contains the line 'fullscreen = true' and the game is started in fullscreen mode and then switching to windowed mode, the problem occurs. If the aforementioned file contains the line 'fullscreen = false', the problem does not occur.
The problem appears to have been fixed, or at least worked around, in the latest release in the Angry Birds series, Angry Birds 2.1.0.
I believe it is a Wine problem as the behaviour is not the same as it is in Windows.
