User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:89.0) Gecko/20100101 Firefox/89.0
Steps to reproduce:
-Enable "Use smooth scrolling"
-Click "New Window" in upper right hamburger menu OR drag a tab outside the window to create a new one
-In the new window, open any website and scroll
Actual results:
Scrolling seems laggy, not smooth anymore. Additionally, the whole site seems to have poor performance compared to sites in the first window.
Interestingly, when the tab of the new window is attached to the tabbar of the first window, performance on this site is completely restored.
Also the bug has nothing to do which screen the window is on.
The bug is new in the 89 Beta, it is not there in Firefox 88.
Expected results:
Websites/Tabs in the new window should be as performant as ones in the first window.

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

I can't reproduce here (on Fedora 34). Can you run mozregression to see when it broke for you? pip install --user mozregression
and then mozregression --good 88
should do.

Hey, I tried mozregression and realized, that the problem must be related to my addons since the problem didnt appear in those builds. I tried starting my browser without addons and the bug was gone. Then I startet disabling and enabling single addons to see which one is the problem. After disabling one of them, the bug was gone. Even after enabling it again, the problem still did not occur anymore. Thats strange, since I had this problem for days and restarted several times, but nevermind. Thus, this issue can be closed since it is not reproducable for me anymore. Thanks for your effort!

Wow, that's a bit bizarre, do you know which addon was this out of curiosity?

It was the "Avira Browser Safety" - addon. I just realized I can safely remove it now since Firefox has most of its features by now :D
