Status: RESOLVED DUPLICATE of bug 2035152

(Core :: Widget: Gtk, defect)

Description

Attachment: 2026-04-25_18-11-48.mp4

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:150.0) Gecko/20100101 Firefox/150.0

Steps to reproduce:

Opened plugin window (Bitwarden) on Firefox 150 running on Hyprland (Wayland).

Actual results:

While Firefox window is scaled correctly on my multi-monitor setup (with different scaling on each), when I clicked Bitwarden plugin its window was too big. Also when I've tried clicking on it the window went under Firefox window - which basically made it unusable.

Expected results:

The plugin window should retain correct scaling and should be usable. Downgraded to previous Firefox version and it works correctly there.

[BugBot [:suhaib / :marco]]

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Since this is a regression starting in Firefox 150, could you please run mozregression to help us identify the exact commit that introduced it?

pip install mozregression
mozregression --good 149.0 --bad 150.0

This will bisect between Firefox 149 (good) and 150 (bad) and narrow down the responsible change. Thanks!

Also can you try different compositor? (Gnome/mutter or KDE?)

May I also have about:support?
