Invisible bookmarks menu and occasional invisible context menu when using wayland window protocol on amdgpu system. Had to downgrade to 72.0.1-1. There are no such problems on laptop with i915.

Usually it's nss depedencies. Resolved white pages with 72.0.1 by manually upgrading nss to 3.48.0-1.fc31 on F31. Same for FC30. Just check "Library Versions" in about:support. "Expected minimum version" should be at lest equal to "Version in use".
