--- Comment #7 from Roderick Colenbrander thunderbird2k@gmx.net 2007-10-14 08:08:27 --- The bug itself is not fixed. To be exact PBOs which are causing the problem are available on 'modern' cards. My recent patches added another codepath (using shaders for color conversion) and for this reason the problem doesn't exist anymore. But I prefer not to close this bug as if you would disable the shader the issue is still around. In some other cases the PBO bug still appears but perhaps not for 8bit.
