--- Comment #8 from Emanuele emanuele.emalele@gmail.com 2011-08-11 07:41:59 CDT --- Dear Mr. Verbeet,
it seems you've solved my issue.
I followed Gentoo guide, created 32bit system into a 64bit one, launched Wine 1.3.26 and not a single glitch is viewable.
This 'bug' can be closed now because the problem disappeared and with Gallium ATI does render really better than with prop drivers.
Thanks again and for anyone who is using Wine... please use 32bit :)
Regards!
