The GL contexts' CreateDrawContext made the thin3d presets and ContextReset made them again, leaking the first set on every context reset. Only ContextReset makes them now. The software renderer draws the same frame dumps on arm64 as on x86-64, so the frametests run on the arm64 runner too. b.sh --aarch64 and setup-cross.sh aarch64 give a headless build to run them under qemu locally.
