It's been a long time, so I'll tell from the beginning again. I used to run Wine on Arch Linux (and other GNU/Linux distributions before) with a single-core, 32 bits Sempron. Then I moved to Ubuntu 64 bits, on a Core 2 Duo processor. I can still run winecfg fine, but now when I run a Windows software with Wine many graphical elements get unrecognizable, mainly text (which is major, since I used Wine mainly to run a dictionary). There's a dump at: http://www.winehq.org/pipermail/wine-users/2009-April/051866.html And I managed to upload an screenshot at: http://leonardof.org/houaiss-com-defeito.png I was told in this mailing list that it should not be a a 64 bits issue, but a dual core issue. I tried "schedtool -a 1 -e wine path/to/exe" and "taskset -c 1 wine path/to/exe" but got thesame behaviour. Could anyone please help me figure this out? Thanks!
