Description Miro Hrončok 2025-06-03 12:05:37 UTC

See https://koschei.fedoraproject.org/package/pygobject3 -> https://koschei.fedoraproject.org/build/20645930 

Since mutter 48.3-2.fc43, the build fails with:

+ xwfb-run -c mutter -- /usr/bin/meson test -C redhat-linux-build --num-processes 6 --print-errorlogs --timeout-multiplier=5
Xwayland failed to start!

This breaks more packages:

That is the case.
