------- Additional Comments From maury.markowitz@gmail.com 2007-29-05 11:08 ------- I have a feeling this bug has been miss-labeled at least in the case of PGIII, and perhaps others as well. Most of the effected applications are fairly old (3+ years) so I find it somewhat hard to believe that they made much use of multi-threading. Further, in my own experience the "black screen" appears in 2D menus, not 3D in-game. While it's possible they are using D3D for these menus, I find it somewhat difficult to believe.
Its possible I just don't understand what this bug report really means. I do know that the Mac OS recently received an upgrade to multi-threaded OGL, is this in any way related? Is the name of the bug perhaps misleading?
