Summary: [r300g][glsl] Textures are black in Xonotic with offset mapping - r300 FP: Compiler Error: r300_fragprog_emit.c::begin_tex(): Too many texture indirections Product: Mesa Version: git Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r300 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: xeros@irc.pl

When I enable "offset mapping" option in Xonotic (new open source FPS game, Nexuiz fork) all the textures are black and I get something like this on console:
