Mozilla bug implies this also happens with Intel GPUs. does it work with R600_LLVM=0 ? (In reply to comment #2) > does it work with R600_LLVM=0 ? No. Quoting the Mozilla bug: "A GL_INVALID_FRAMEBUFFER_OPERATION error is generated in glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT|GL_STENCIL_BUFFER_BIT). glCheckFramebufferStatus returns GL_FRAMEBUFFER_INCOMPLETE_MULTISAMPLE." Keep in mind that this renders correctly with AMD Catalyst drivers. To be more accurate, Google Maps attaches a depth and stencil buffer with 4 samples and a colorbuffer with 0 (1) samples. That's clearly not supposed to work. I do not believe this is a bug in Mesa. This is a bug in Gecko. |
