I guess this is the same bug as mentioned here? http://lists.freedesktop.org/archives/mesa-dev/2011-January/004888.html Doesn't seem to happen with llvmpipe fwiw. (In reply to comment #3) > Can you try the patch on bug 31940? Patch from bug 31940 doesn't help. |

Created attachment 42102 [details] full backtrace When running WebGL test runner with r300g there is: Program received signal SIGSEGV, Segmentation fault. 0x02650ab3 in dri2FlushFrontBuffer (driDrawable=0xb0e91200, loaderPrivate=0xa2afb020) at dri2_glx.c:460 it doesn't always crash at the same test but it is 100% reproducible when you click run tests and wait. This is with mesa: d136d1d2e1174d2420ce5e32507904243ab240cd kernel: 2.6.37 GPU: RV530 Firefox 4.0b8 Firefox must be started with MOZ_GLX_IGNORE_BLACKLIST=1 (acceleration is disabled by default for mesa because of crashes). You also need to set webgl.enabled_for_all_sites to true in about:config. I'll try to reproduce this with some other driver.
