Fair enough, though it shouldn't be hard to write a simple app to test the reparenting / compositing without any special OpenGL requirements? > How exactly could DRI2 make a problem with the cat driver? DRI2 is not the problem, it's a possible solution. :) One of the main motivations for creating DRI2 was that the original DRI couldn't properly support compositing. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer
