Created attachment 74497 [details] screenshot In the Car Visualizer Webgl demo, there are some flickering black spots on the car. This is probably a bug in the shader compiler, as RADEON_DEBUG=noopt works around this. Specifically its the register_rename pass that causes this, when it is disabled in r3xx_fragprog.c, everything is fine. Also when I disable only the dataflow optimize pass, there is still some flickering but much less. Firefox 18.0 GPU:RV530 Mesa: 0e2f26d5ea26febd16173aa8bbf7427b090e320f Kernel: 3.7.3-101.fc17.i686
