--- Comment #21 from RJVB <[email protected]> --- There is a rather evident workaround (which I ended up applying myself). The Mesa culprit is the (gallium) LLVM-accelerated software rasteriser (swrast). I think this is typically used only for OpenGL operations on a remote display, but Mesa also comes with (or can be built to provide) a non-accelerated version. Remove or uninstall the accelerated driver or rebuild Mesa (with --disable-gallium-llvm --disable-gallium-llvm) and the problem goes away. With a reasonably modern CPU you shouldn't notice much of performance drop in the desktop eye candy that uses OpenGL. Sorry that I cannot be more specific, I did this months ago and didn't take note exactly how. It seems I simply rebuilt Mesa without the gallium-llvm stuff in a launchpad PPA. -- You are receiving this mail because: You are watching all bug changes.
