--- Comment #6 from iam@valdikss.org.ru 2011-08-18 00:40:09 CDT --- Created an attachment (id=36030) --> (http://bugs.winehq.org/attachment.cgi?id=36030) sysprof log
Here is a sysprof log. As you can see in the log, drm_get_edid takes all the cpu time and causes mouse shutters and everything. So I think this is a driver bug, but it works only in wine. I'll make a bugreport at freedesktop.
