http://bugs.winehq.org/show_bug.cgi?id=59631 --- Comment #27 from Stian Low <wineryyyyy@gmail.com> --- In summary, in case it was not clear from previous comments: Prior to recent DCompositionCreateDevice patches added to wine-staging, it seems Battle.net would fallback to alternative rendering method that uses swap effect 0x1 and only 1 back buffer. Therefore DCompositionCreateDevice support seems to have activated a different rendering method that is used instead of alternative fallback when available and uses swap effect 0x3 with more than one backbuffer which is not well supported. Therefore alternative rendering method without DCompositionCreateDevice seems to be the basis of how wine users expect Battle.net to behave and may be useful as a reference for dev fixes to DCompositionCreateDevice so that users eventually are barely able to tell the difference between the two rendering methods. Merge request patch intended to fix discrepancies for swap effect 0x3 and more than 1 backbuffer does not work when combined with wine-staging DCompositionCreateDevice patch so more work is needed for compatibility. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
