--- Comment #1 from Roderick Colenbrander thunderbird2k@gmail.com 2010-05-07 09:57:34 --- The log shows a lot of driver messages related to FBOs. In Wine versions before 1.1.23 we didn't use FBOs by default for offscreen rendering but as of 1.1.23 we do but FBOs are still buggy on some drivers. It might be that the issue you are facing is a driver bug in the FBO code. You could try what happens if you set OffscreenRenderingMode to 'backbuffer' which is what we used before.
