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.

Hello,
I am not a sidebar user, I don't want it visible and automatic hiding is annoying since the sidebar appears mostly when I don't want it (when I randomly get nearby with the mouse). I want to use Aria though. When I set sidebar to be hidden and then open Aria by highlighting a text on web and using one of the AI commands from the small menu, use Aria and close it, then the sidebar is automatically switched to be visible again. The expected behavior would be that after closing Aria, the sidebar would disappear again and stay hidden. In other words, I'd expect the "Show sidebar" switch not to be changed after using Aria.

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.
