The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.
Please try latest nightly under Wayland:

Thanks.

This morning successfully reproduced the bug: the laptop was last time used as a standalone, so in 125% scale, then suspended.
This morning before waking up laptop, connected the external monitor.
Upon wake-up firefox was totally scrambled on the screen, had to be restarted

Thanks.
Unfortunately ubuntu 20.04 does not have wayland enabled yet, es of my understanding. I have just one linux machine, and that's ubuntu 20.04

Though Ubuntu does not default to Wayland yet (will probably do so by 22.04 LTS), you can choose whether to enable it at login: https://bun.filedit.ch/gOmRWgwiGTAiIbyJzTAA.png. With that, please take a look again if you can reproduce this bug when following https://fedoraproject.org/wiki/How_to_debug_Firefox_problems?rd=Bug_info_Firefox#Testing_Mozilla_binaries.
