--- Comment #1 from Roderick Colenbrander thunderbird2k@gmx.net 2007-10-10 09:14:58 --- I have no idea what it can be. At least the bug is not OpenGL related as it happens in both OpenGL and Direct3D mode. I have also checked if it depends on the font but all fonts show the same behavior. It must be somehow in the font rendering code or perhaps gdi.
