Using a virtual desktop doesn't help.

Btw, where in the code is the "set off screen: invalid drawable" message triggered? I searched for it, with the hope of being able to fix it, but it seems that message isn't in the Wine source code.

And, how are you rendering offscreen? With pbuffers? If affirmative, I believe pbuffers aren't supported in Apple's GLX, but framebuffer objects (FBOs) are supported. Can I try to rewrite the pbuffer code and translate it to FBOs, or would it take thousands of hundreds of code lines?

Anyway, first of all, I need to be sure what lines in the source are triggering the above warnings, but searched the source without success. Any advice for finding them?

Thanks!
