cpu spikes while using mouse on YouTube

Zojj

I have installed Vivaldi a few days ago and I have a problem with using YouTube. Normally, when I play a video on YouTube my cpu usage is somewhere around 3%. The instant I start hovering my mouse pointer above the player or the side panel with recommendations, cpu usage spikes to about 60% (which is annoying because fans start spinning in my laptop). When I stop moving my mouse, after a few seconds the cpu usage gets back to normal. Any ideas what can be the cause of this?

Hi, maybe an extension cause this ,test this in the guest view.
Vivaldi://gpu looks fine to me.

Thank you for your reply. I have already tried this as one of the steps described in: https://help.vivaldi.com/desktop/troubleshoot/troubleshooting-issues/
In the guest view the problem is exactly the same. What else can I try?

@Zojj
I can only guessing now, nobody else reported such an issue iirc.
Do you have a special mouse, track ball or something?
Some user report issues with a 5 key mouse, respectively the driver and Vivaldi.

@mib2berlin said in cpu spikes while using mouse on YouTube:

I have logitech g102. I have also tried disconnecting mouse, restarting browser and using trackpad instead. The high cpu usage remains. I've also noticed that if I just leave my cursor on the red line indicating the progress of the video (while the video is playing) the cpu usage jumps to 45% and stays like that until I move the cursor somwhere else. Scrolling through youtube feed results in the same behaviour.

I am sorry, out of ideas.
Testing this with playing a 4K video in full screen and on my second display scrolling through a Youtube page, the CPU is max. 20% and I have a AMD Ryzen 7 iGPU not such a powerful GPU as yours.

Cheers, mib
