Thanks, r_drawflat 1 check was the ticket. It didn't affect the gray void, which ruled out a lot of things. So with some testing I found the exact build where the debug is broken and am looking at the diff.

Hopefully the "release-only" side of the issue will clear itself up when the boo-boo is found! Otherwise will try the screaming thingy.

Quake's video mode changing is a mess anyway. And not everything is recalculated on the correct order, so I'm getting video aspect problems in my engine when switching between some resolutions. Updating the video aspect from the menu fixes that, but is not a true solution.

There's a lot of work to be done on that.

Gcc has a known history of goofing up with agressive optimization
some versions Work some dont so as a rule of thumb i allways use O2 and specific optimization options to rule out the optimization switches that fail.
4.8.0 has a bug with O3 optimization producing bad results i hope 4.8.1 will have it fixed when it comes.

It was very specific ill see if i can dig up the bugzilla id but it was also causing some trouble for me with some code that other compilers handled well.
Btw i hear rumors that lto broke with 4.8.0 on Windows gonna check it tomorrow as its quite late here now

I think it was this one i remember i couldnt get the code to run unless i added -fwrapv to the -O3 optimizations, it seems to be caused by the switch from ppl to isl optimization libraries. There was also a bug in current release binutils (cant remember bug id) that caused nm to fail generating symbols for dll builds so the compiler i provide comes with the latest
cvs version which has that fixed (does not affect exe builds so should be fine for quake but better safe than sorry). 4.8.0 still has a rather large list of serious regressions which will hopefully be fixed with 4.8.1.

4.8.0 is neither worse nor better than many compilers in fact gcc mostly does a better job than msvc but this release features a slew of new additions like SSE (64 bit only) so its predictable that there might be some bumps in the road.
