Voodoo3 only. May be related to glDepthMask - or glColorMask. - -book/fog - not fogging - Fog in orthograph mode still not implemented. Checking with - 3dfx engineers for ideas. - -Q3 demo crashes after changing display settings - but the full Q3 game version seems OK. - - - -MORE OUTSTANDING BUGS - -private context was NULL! causing immediate failure of any glx prog. cant -reproduce after restarting the X server. putting it down as halluc. - -texture object image was NULL, causing segmentation failure. happens with -prboom. ive put a check in tdfx_texstate.c but this isn't a fix. - -prboom, wall textures near first chainsaw aren't bound properly. sideways -movements causes the wall textures to move with you. prboom busted? - -16bpp mode, quake3, windowed, q3dm1, floor under rocketlauncher bands. it -looks like multitexturing gone wrong. i'll disable a tmu and test. - -sof, polygons appear at wrong x,y,z positions, intermittent, have not yet -found reliable way of reproducing. culling? sometimes polys disappear. -
