Screenshot of bug

Turning on shaders in the game M.A.R.S. results in a mostly pink background image, which is an obvious misrendering.

This is probably a regression in glsl2 (swrast from Mesa 7.8 seems to work okay).

The game only uses two shaders, available here:
http://mars-game.svn.sourceforge.net/viewvc/mars-game/data/shaders/

I'm using git master, dbf996f30856c000e18e3700f741d4e92561b4ec

Comment 1 Sven Arvidsson 2013-09-18 11:11:43 UTC

Still a problem with latest version of the game 0.7.4 and Mesa 9.2. Turning on shaders locks the display, but the game seems to continue running.

On i965 I get:
 
 intel_do_flush_locked failed: No such file or directory

On r600g I get rejected CS with the following in dmesg:

I've tried to run precompiled binaries of the game but the ones from rpm and ones from zip relase have symbols that are not present in the bundled libraries or libraries from my OS (fedora19). I'm having also problems compiling the game, cmake configuration passes ok but compilation fails due to SFML headers not found correctly. Is there a known working 'zip release' (like mars_linux_0.7.4.tar.gz) of the game with all the deps included?

I had a quick look at this. Debian ships version 0.7.5 of the game, which does not seem to have been released anywhere else, but in this version the shaders seems to work fine.

Next I tried getting an apitrace from version 0.7.4, but replaying the trace does not trigger the bug.

Not sure if it's any point in keeping this bug open any longer.

OK, I'll try to get the version Debian ships to verify. I can't spot anything from shaders that would not be supported, the issues are very likely gone.

tested Mars 0.7.5 on debian jessie with Mesa master and shader effects enabled, graphics work fine, resolving as fixed
