Firefox - laggy scrolling since 98.0.
OS: ArchLinux DE: i3wm, X11 GPU: GTX770, Kepler, proprietary nvidia driver Firefox version: 98.0(64-bit)
Hi! Since updating Firefox to 98.0 I've been experiencing sudden performance drops(lags/freezes/stutters) while scrolling. `about:support` page shows that compositing is `WebRender`. The issue occurs with fresh profile without any addons installed and also in `firefox-nightly`(100.0a1). However, scrolling is totally smooth in 97.0.2 and earlier versions of Firefox.
What changes in Firefox 98 could cause this, and are there any settings in `about:config` I can try to tune to solve the issue? These are the settings I've always used, and, as I mentioned, scrolling was smooth before 98.0:
gfx.webrender.all = true
general.smoothScroll.mouseWheel.durationMaxMS = 400
general.smoothScroll.mouseWheel.durationMinMS = 200
mousewheel.min_line_scroll_amount = 40
mousewheel.system_scroll_override.enabled = false

Try downloading another copy of Firefox, run it from the folder and see if you have the same issue. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release
@jonzn4SUSE, Thank you for the response, but, unfortunately, it didn't help. I've also created a report at bugzilla, but it seems no other users can confirm it yet:
I would log into another account and see if Firefox has the same issue. Also try a different desktop environment or try a Live image.

I've tried Gnome and KDE - the same results. Maybe this is something Nvidia-related. When start to scroll, it might be smooth for a while, but suddenly "lag mode" turns on and everything becomes slow and choppy. I've also tried switching to free driver, but in this case I have to enable software vsync in a compositor like Picom, that makes things even worse. Switching back to Firefox 97 solves the issue completely.
Interesting...
I'm seeing the same issue since the latest update (101.0.1 on Windows 11). Multiple sites the scroll either from the trackpad or on the touch screen locks and is laggy. Very frustrating and introduced recently.
