--- Comment #2 from Sebastian Lackner sebastian@fds-team.de --- Thanks for the bug report. Actually, one of the main reasons for the commit was to improve performance, but since this doesn't seem to work out for all graphic cards / drivers, I have decided to disable it again. Please let me know if the issue is still present in current Wine Staging git. Also, it would be interesting to know which hardware / driver combination you are using.
