[Dri-devel] "Depth fighting" with lightmaps...

[Robert F M. <gr...@t2...>]

since I updated DRI from a really old version (latest for X 4.2), 
quakeforge has been having this
bizarre problem where textures will occasionally flash patterns of white 
dots... as far as I can tell
this is caused by the lightmap depth-fighting with the regular texture, 
which is very odd since
lightmaps are transparent.

This doesn't seem to happen in other games, I guess because other games 
always use multitexture, however it doesn't
happen with glqwcl either.

I know that you consider depth fighting problems to be the application's 
fault, but the QF people say it's
a DRI bug...

this happens even with TCL set to software, which doesn't really matter 
since for some reason the driver
is NO-TCL (??).

I'm a bit of a DRI newbie, so please point out anything I'm doing wrong
