Opera UI 60Hz Refresh Rate/FPS

Has anyone else noticed that the refresh rate of the Opera UI is locked at 60Hz/FPS? Using Opera on a high refresh-rate monitor is really jarring when you're using to anything higher.

This issue is only present in Opera. Other browsers I've tested with are Firefox, Vivaldi, Chrome, Brave and Edge, of which all run smooth!

Are there any CLI switches that remove this limitation?

This issue is bug DNA-68444 that was filed in March of 2018. Opera bought some 240Hz monitors just to test. Long story short, no one at Opera was able to reproduce the problem. Opera's UI was not laggy and it behaved the same as Chrome's UI.

Also, see https://forums.opera.com/topic/24026/ui-is-laggy-only-runs-at-60-fps-on-144-hz-monitor and https://forums.opera.com/topic/19574/ui-elements-are-laggy-and-animate-at-only-60-fps-on-144-hz-monitor.

There's also https://www.reddit.com/r/operabrowser/comments/59qbe0/no_longer_hitting_144fps/, which has a test that Opera passed when testing. But, that was in a web page and not the UI.

In short, this is unlikely to get fixed as no one can reproduce the problem.

Using the arguments here made it possible to run Opera in higher FPS according to my monitor (240Hz). Confirmed here. Not sure if it's the same problem but this is the best we can get I guess.

Quick update that I have posted also to the chromium bugs. This is Linux solution! This command in terminal fixed my problem:

xrandr --output DP-2 --rate 240.0 --primary --mode 2560x1440

Run xrandr with no arguments to see what output you have connected etc. and fill your resolution. I have added the command to run at startup. This sets the rate correctly so the browser can then run with it.
