--- Comment #12 from Roderick Colenbrander thunderbird2k@gmx.net 2008-04-30 12:45:27 --- I have the bug too when I'm using a compositon manager (compiz, desktop effects enabled in kde4). It is normal that you get the error then as we use the same mechanism to render to 'opengl views' as the mechanism used by compiz to create 3d effects. Composite calls can only be made on a window by one client, so wine and compiz are stepping on each others toes.
