This is a problem with experimental partial scaling. The menus are correct when scale 1x or 2x is used, correct?

This is weird. The huge hamburger menu that I was seeing with 1.5 scaling in yesterday's nightly has been fixed today. Is this an intentional change that fixed this? 2x scaling sort of works in the sense that the menu is scaled correctly, but it does not make use of the entire real estate of the screen. Instead it comes down about 2/3rds of the page and puts a scroll bar on the menu. To re-iterate this is only the hamburger menu, regular menu items are working fine.

Can you please attach a screen of the broken firefox with 2x scale? I use that every day on my own box and I don't see any issue here. The 1.5 scaling is managed by wayland compositor, it's not handled by Firefox itself, Firefox handles only non-partial scales.
Also which distro/DE do you run?
Thanks.

I figured out the cause of the problem. The scaling of menus, popup windows etc. in Firefox gets messed up if I hot plugin an external monitor with a non default scaling after Firefox has already been running. Once the external monitor with 2 or 1.5 scaling is plugged in, in order to get the scaling of these elements right, I need to restart Firefox. Once restarted everything is fine again.
I'm using Sway on Archlinux. Let me know if this is a Sway issue, I'll report it there.

I think it's a sway issue when wl_output is not updated. Can you please try mutter/gnome if you can reproduce it?
Thanks.
