Corrupt or Missing Text in 0.9.25 and 0.9.26 - here's the fix for ATI cards
Open a terminal window, (konsole/terminal/x terminal etc..) and type regedit. This will start the wine server
and the wine equivalent of the windows registry editor will be displayed. If your familiar with using the registry
editor under windows then this is pretty much the same.
Highlight the wine folder in the left hand pane by clicking left on it. The icon should change to an open folder
Click right on the wine folder and select [NEW] then [KEY]
Replace the text "New Key #1" with OpenGL
Click right in the right hand pane and select [NEW] then [String Value]
Replace "New Value #1" with "DisabledExtensions"
(Notice it's case sensitive)
Then double click anywhere on the line, a dialog box will open.
In the value field type "GL_ARB_vertex_buffer_object" (without the quotes).
