I might be seeing something similar on my i945gme. I'm trying to get x-tiling (using tiling bits) to work in the i915 gallium driver. It seems to work rather well (given the state the driver is in, generally), safe for something very odd: When I relocate textures with NEED_FENCE (still using tiling bits in the command stream), the fbo texture renders all black in fbo_firecube. Relocating without NEED_FENCE works flawless. Latest -linus seems to be affected, too. This is just fyi, I have currently no clue what's going on and I'm still investigating. -Daniel -- Daniel Vetter Mail: [email protected] Mobile: +41 (0)79 365 57 48 _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
