Its been few months and the problem is still there. I'm a little used to it now, and im trying to only open messenger on my phone. But sometimes i forget and boom, my Opera GX starts to use 70% of CPU. Then i have to close it and open again.
At one point the same problem also did twitch and youtube, but with much smaller percentage of happening and it was probably solved, because it didnt happen in few weeks.

@leocg I tried now, and yes. Mainly opening unreaded messaged does this CPU problem

@leocg Oh, i probably found out what is the problem. When i open the messenger tab on side panel, or mainly when someone sends me a message through messenger, the CPU usage drastically go up, so probably in some of the last updates the messenger in Opera got broken or something

@leocg Here it is just saying "Browser" and the something called "Worker - www.messenger.com". Those two are the only tasks that shows CPU over 100.

Hello.
Past few days, my Opera GX started to use 30 - 40% of CPU (50 - 70% if all other apps are closed). It usually starts after few hours of running normally. When i start my PC and start Opera GX it uses only 5% of CPU max, then, after few hours it goes to somewhere between 30 to 70% CPU usage and never drops below. When i close and start Opera GX again, the usage is now normal (max 5%).
Is this some bug after new updates, or is something else wrong? I didnt made any changes to Opera GX settings, mods, or extensions
