I've update my Ubuntu Gutsy to Hardy (7.10 -> 8.04) and Wine 0.9.somthing to wine-1.0-rc4. I've the lastest ATI proprietary driver installed.
Before, I could run WoW without any problem in OpenGL except the buggy minimap when I entered in a closed area map (a tavern, or a cavern, etc.), the minimap became blank... (before: Gutsy, Wine 0.9.6x, ATI Catalyst 8.1, after: Ubuntu Hardy 8.04, Wine 1.0rc4, ATI Catalyst 8.4, ATI HD3850).
Now, when I enter in a closed area, I've something like :

It's very annoying

Only the first character of a string is displayed, the rest of the string is bugged.
When I get out of the area, I need to reinitialize my video configuration (by changing antialising for example) and I recover a good image without error. When I enter again in a closed area, the screen is bugged again...
I've changed to Direct3D and I've a lot of errors (vanished walls, etc) but the strings appear normal.
Do you have an idea ?
Thanks
