Using modular X 7.0 from ~x86 and prboom 2.2.4-r1, with USE=opengl I can't see sky in any level. Instead, there is plain white background with no pattern whatsoever. There is always one vertical strip of the sky light gray instead of white. Sometimes it is narrow, only some 1/10th of the field of vision in width. Sometimes its widht is half of the field of vision. That changes from map to map, but it stays the same during a certain map. The video card is a Matrox G400 and direct rendering is enabled.
prboom 2.4.1 has the same problem
how about 2.4.3?

No reply.
... and works for me with the latest.
