It sounds like something is not configured correctly. If your GL_RENDERER string doesn't look like "Mesa DRI Intel(R) Ivybridge Mobile" (or whatever your Intel chipset actually is), the wrong driver is being used. Also... 10.2.* is fairly old at this point. 10.4.1 was just released. Can you try a more recent version of Mesa? Maybe Kristian or Jason can offer some advice on how to configure things correctly. I just tried with mesa 10.4.0 and xwayland 1.16.99.901.115.g6672606. I had to add +iglx flag to xwayland parameters to get glxpixmap running since indirect glx context is disabled by default now. And xwayland still crashes. Dear Reporter, This Mesa bug has been in the "NEEDINFO" status for over 60 days. I am closing this bug based on lack of response but feel free to reopen if resolution is still needed. Please ensure you're supplying the correct information as requested. Thank you. |

Xwayland now uses dri3 and glamor as means of acceleration. However, glxpixmap (uses indirect rendering context) shows it uses software rasterization on intel hardware: GL_RENDERER = Gallium 0.4 on llvmpipe (LLVM 3.4, 256 bits) Moreover, Xwayland will crash when glxpixmap exits (backtrace is listed at the end). It segfaults in st_renderbuffer_delete in src/mesa/state_tracker/st_cb_fbo.c where struct st_context *st = st_context(ctx); pipe_surface_release(st->pipe, &strb->surface); st on the first line is NULL and it is dereferenced on the second line. It can't be reproduced with vmglfx since it lacks support for dri3. But I didn't test nouveau or radeon because I lack such hardware.
