I applied a mutter patch written by Marco Trevisan and uploaded to a PPA: https://launchpad.net/~gunnarhj/+archive/ubuntu/mutter
With the binaries from that PPA build I can no longer reproduce the black window issue described in this bug. Not even after having run: killall Xwayland So I pushed the patch to the repo. https://salsa.debian.org/gnome-team/mutter/-/commit/a400e60d ** Changed in: mutter (Ubuntu) Status: New => In Progress ** Changed in: mutter (Ubuntu) Assignee: (unassigned) => Gunnar Hjalmarsson (gunnarhj) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xwayland in Ubuntu. https://bugs.launchpad.net/bugs/2016918 Title: Firefox snap opens a black window on wayland To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/2016918/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
