--- Comment #28 from Roderick Colenbrander thunderbird2k@gmx.net 2007-10-31 07:42:15 --- Just leave the bug open. Perhaps I'll take a look at it later today. Basically the problem is that Jazz Jackrabbit II requires color depth conversion which can't be done when PBOs are active. PBOs are active and this is roughly what causes the problem. (color conversion requires access to memory; in case of a PBO you can't always access the memory)
