In attached GIF you can find, what is wrong with OpenGL rendering.
It's tested with 8.0-dev mesa, latest commits seems to be:

This screenshot shows (safe-mode) how game is expected to look.
Please compare to blinking GIF. This picture shows what is expected.

Missing textures. This is not animated version, captured when textures were blinking.

Current git crashes Xorg
I tried recent commits in mesa, and I experience Xserver segmentation fault crash.
I am a bit worried since its release candidate and content is deteriorating. I hope it wont be release until critical bugs are fixed.
I tried bisecting, but because of introduced bugs in building process on some machines in git history, its not possible to bisect (sorry!!).
I tried debugging Xserver from ssh, from another laptop (see attachment).
If you have any ideas, how to find out why Xserver is crashing, please let me know, so I can test RegnumOnline textures bug.
Ok Xserver does not crash anymore, I installed one from Debian Experimental.
It does crash with Xorg from Debian Sid.
So please ignore, last attachment. But Texture bug is still present, so please leave this bug open.
Okay, I can reproduce this. I've managed to capture an apitrace which demonstrates the bug so we can debug it without needing the game and an account.
Now to trim it down and figure out what shader's going wrong...

That's a good news, so there is a chance it will be in mesa 8.0 ? I keep fingers crossed. If you commit fix, I will test it. Thanks.

Textures broken in left corner
With git mesa as of the moment of writing, the problem is almost gone. Blinking is gone. But sometimes I see still some rare artefacts on the sides of the screen, or trees (attached screenshot).
In general most annoying bug seems to be fixed, maybe those small texture problems are related to other condition ?
Thanks for fixing.
same issue on radeon drivers. (mark as duplicated if is needed)
Problem is NOT gone, it was custom patch from Kenneth, but after git clean, I see that it hasn't been merged, and game is still not playable.
I would be grateful if your patch could be merged.
The original flickering issue is gone. From playing a few minutes of the game, it appears to be working just fine with Mesa 8.1/master.
If there are further issues with Regnum, feel free to report them...
