Attachment: motionmarkresults.png

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:136.0) Gecko/20100101 Firefox/136.0

Steps to reproduce:

Run Motionmark 1.3.1 on a large screen (desktop) in Firefox Flatpak 136.0.3 (occurs in previous version as well).

Operating System: Fedora Linux 41
KDE Plasma Version: 6.3.3
KDE Frameworks Version: 6.12.0
Qt Version: 6.8.2
Kernel Version: 6.13.8-200.fc41.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 8 × Intel® Core™ i5-10210U CPU @ 1.60GHz
Memory: 15.3 GiB of RAM
Graphics Processor: Mesa Intel® UHD Graphics

Actual results:

Constantly getting scores below 200 with large variations.
Most recent result:
Total - 193.40 @ 60fps (+-75.36%)
Multiply - 25.00 (+-3104.00%)
Canvas Arcs - 8.00 (+-25.00%)
Leaves - 31.00 (+-87.10%)
Paths - 1820.52 (+-93.39%)
Canvas Lines - 12491.50 (+-6.27%)
Images - 111.83 (+-4.40%)
Design - 141.26 (+-18.11%)
Suits - 879.00 (+-91.47%)

Expected results:

Multiply, Canvas Arcs and Leaves shouldn't be so low and have high variations.

In Zen 1.10.1b, I am able to get 561.02 @ 60fps (+-10.24%)
In Vivaldi 7.2.3621.67, I am able to get 881.47 @ 60fps (+- 3.86%)

All of the above are using their Flatpak versions. Attached are screenshots of results (from top-bottom: Firefox, Zen, Vivaldi)

[BugBot [:suhaib / :marco/ :calixte]]

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.

May be related to Bug 1907266? Is that Fedora Flatpak or flathub one?

Mike, any ideas here what's going on with the build and if like in bug 1907266, PGO maybe has something to do with it?

Heyo, sorry for the late reply.

After a few hours of troubleshooting (refreshes, safe mode, testing on zen browser), it seems that the regression is completely unrelated to the bug mentioned, but is instead caused by the Bitwarden Extension. The build I'm using is from Flathub and not Fedora Flatpak.

I'll file a separate report to the Bitwarden developers regarding this, but its up to you guys to see if you want to investigate this further or close the issue.
