--- Comment #17 from Alexey Loukianov mooroon2@mail.ru 2011-11-17 15:13:53 CST --- Please do not confuse original bug which is only about some effects that had been rendering upside-down - and not the whole "game world" - and it had been happening in pretty small number of apps (confirmed to occur in all Source-based games and at a pretty minor place in "King's Bounty" series) - and not in each and every app out there. Would you please test it in some Source-based game to prove that's it is the same bug flashback and not a newly introduced independent one? I would be able to test it in HL2-series myself but non earlier than tomorrow evening.
P.S. In case Skyrim had been working correct with older versions of Wine - doing regression test and reporting a new bug would be your best way to proceed. P.P.S. Thanks for spending your time and reporting this issue.
