• Popups are wrongly places

[Jan Alexander Steffens [:heftig]]

This could be the difference in behavior of wl_output between physical and logical layout mode, which causes GdkMonitor to report bogus sizes. This is fixed by https://gitlab.gnome.org/GNOME/mutter/merge_requests/510

Some popups are also wrongly sized — the Site Information (security) one, specifically. It's rendered for 2x but sized for 1.5x, so it becomes horizontally scrollable.

The placement is correct most of the time for me (using Wayfire, a wlroots based compositor), but sometimes e.g. the main menu appears way off to the side.

Both are recorded in this video

looks like bug 1490297 is about the same thing

Yes, I can confirm although I need to restart browser after the change as there's Bug 1554850.
Closing this one as WFM as we can't do anything else on Firefox side.
