--- Comment #4 from Lars Blomqvist knaprigt@gmail.com 2009-06-05 09:55:49 --- Ok, I've finally found a solution for this one. It turns out that the problem is fixed by setting "Sync to VBlank" for OpenGL to enabled with nvidia-settings (settings manager for Nvidia cards), so I guess this isn't really a Wine bug after all.
I've no idea why this only effected the main menu and inventory or Call of Cthulhu and nothing else in the game, but then again I'm no expert when it comes to OpenGL and the use of Sync to VBlank.
The bug should probably be closed (again).
