Because this bug's Severity has not been changed from the default since it was filed, and it's Priority is -- (non,) indicating it has has not been previously triaged, the bug's Severity is being updated to -- (default, untriaged.)
Wouldn't it be enough to apply a patch like https://hg.mozilla.org/mozilla-central/rev/3fe51c2cecad?

Is there any progress on this? I suppose many Linux users with hiDPI display rely on layout.css.devPixelsPerPx to scale the UI. It's been months with a broken browser experience for them. If there's anything I can do that does not involve writing code, I am happy to help.
Here two patch files, back ported some code from: 57400551129c73bf1a5b738e7fa03d331c02601d.
Tested with firefox-80.0.1, wayland and config layout.css.devPixelsPerPx = 1.25.

Jan, can you look at them? I'm afraid the anchor changes may introduce a regression when popup is moved on screen edge but I may be wrong.
Thanks.

I've tried the patch, but unfortunately we cannot accept it. It fixes the devPixelsPerPx issue but the regression is with menu overflow as they are not starting under the menuitem but rather from the top of the screen. We need to use the anchorRect for that.

Yup, I'm one of those Linux users. I am on Sway/Wayland and Arch Linux. I haven't been able to use Firefox with my 4K display and Wayland enabled. My C++ skills are beyond bad, so I don't think I can help with the bugfix.

The milestone at the top of the bug report indicates that this issue was resolved for the Firefox 83.0 release. I can confirm that this bug has been fixed for me ever since: https://i.imgur.com/5I8ptdz.png.

My layout.css.devPixelsPerPx was set to 1.16 which causes the bug to occur still, but doesn't change the size when compared to 1.15. So using 1.15 as the value fixed the issue for me. Thank you.
