You have the misfortune to be using a big-endian CPU, and that corruption looks quite a lot like the vertex processing stage getting channel order wrong. Since the internals of both TGSI and NIR ought to be endian-indifferent, I suspect the error would be at point where you acquire the vertex data from the app and need to do machine-specific unpacking, but that's just a guess. Dumping the IR generated by each should hopefully be instructive. It might also be worth trying to build Mesa 20 against LLVM 6 to see if that points to anything in LLVM, but that's probably a bit less likely. - ajax ___ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
