Dandan, Thank you for the screenshots and testing.
I would prefer to avoid doing further 46.x uploads for mutter; instead I am working to getting GNOME Shell & Mutter 47 into Debian Unstable this month. We are unwilling to completely ignore build test failures. We are going to need a more targeted fix, possibly only ignoring the 2 tests that fail. Here's a snippet from gtk4's debian/rules. Could you try adjusting this for loong64 and see if running the mutter build with softpipe avoids the test failures? ifneq ($(filter mips% powerpc riscv% sparc%,$(DEB_HOST_ARCH_CPU)),) $(info Disabling use of llvmpipe on this CPU, see https://bugs.debian.org/993550 and https://bugs.debian.org/1080435) export GALLIUM_DRIVER=softpipe endif Jeremy Bícha
