Details
User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0
Steps to reproduce:
-
Open https://old.reddit.com/r/india/comments/mg0l3x/sensitive_data_of_more_than_35_million_indians/ or any other page thread on old.reddit.com.
-
Try scrolling up/down or zooming in/out on the page.
My setup is, 5900x/3080/1440p@144hz main monitor/1080p@60hz on X11/Arch Linux.
The performance of scrolling/zooming in/out is 99% of the time terrible(compared to chromium) but when it gets significantly worse, 9 out of 10 times, I have a video playing on the 60hz monitor from Youtube/Vimeo.
Actual results:
It stutters a lot.
Graphics performance from FF Profiler sample #1, https://share.firefox.dev/3dAalP5
Graphics performance from FF Profiler sample #2, https://share.firefox.dev/2PgSrIQ
Expected results:
Scrolling or zooming in/out on these sites should be a relatively smooth operation.

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

Moving it to the Graphic component since this is likely a graphic issue.

Reporter, do you still see the issue. That page linked in comment 0 is very smooth for me on Linux.
And could you try without addons?
And maybe try even https://www.mozilla.org/en-US/firefox/channel/desktop/#nightly ?

Yes, I still have this issue.
FF 88 with all the extensions I use, https://share.firefox.dev/3aVmxcG
FF 88 with Bitwarden, uBO, tampermonkey disabled, https://share.firefox.dev/2QLpQfC
FF 88 with Bitwarden & Tampermonkey disabled, https://share.firefox.dev/3xDJElM
FF 88 with no extensions, a fresh profile & Just 1 tab, https://share.firefox.dev/3uaCDH5
FF 90(current nightly) no extensions, fresh profile and 1 tab, https://share.firefox.dev/33cPSe9
Without any addons and very few tabs, Performance appears on par with other browsers. With 2-3 addons and probably ~100 tabs, Performance drops a lot.
It is also quite confusing to figure out if there are any extensions that are causing this problem. For example, Just now disabling Bitwarden, Tampermonkey and uBO appears to have improved performance but in the past, Disabling these extensions didn't had a significant impact. In the past, It was disabling the old reddit redirect extension that helped me improve performance.

Hi! The answer to this question is, No.
When I created this issue, I was using 1 1080p@60hz monitor and 1 2560x1440p@144hz monitor with X11 in Arch linux. Since then, I have switched to using 2x 2560x1440p monitors(1 supports up to 165hz while 1 supports 144hz refresh rate and I run both at 144Hz). I have not had this problem since I switched to using monitors at the same refresh rate. I am guessing it might be X11 related but I don't really know. Please feel free to close this issue.
