http://bugs.winehq.org/show_bug.cgi?id=15232 --- Comment #9 from Henri Verbeet <hverbeet(a)gmail.com> 2010-04-06 11:07:58 --- I don't know if there are issues with the basic approach of using a clipmask, but I can't think of any. As for the specific implementation, it forces gl_copy for cases where it isn't needed, and recalculates the clipmask on every SwapBuffers() call. Both aren't going to help performance. The gl_copy path should be limited to the cases where there are actual child windows to clip by, and updating the clip mask should only happen when those child windows are created / destroyed / moved / etc. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
