--- Comment #2 from fossphreak@gmail.com 2012-10-27 14:05:43 CDT --- Sorry for the late reply, it looks like it works now when desktop effects are enabled. However, there is another problem, when another program, for example this browser is open, and I enable desktop effects, only the wine window is displayed (I have set Wine to emulate a Windows desktop with a resolution of 1366*768, so it covers the entire screen) and I am unable to switch to any other program.
When I turn off desktop effects, I am able to switch to other programs.
I am using Wine on a laptop, with a Radeon HD 6650M graphics card and with the AMD Catalyst 12.11 beta driver.
