@leocg sorry, it's CPU. I got confused because the page shows "Out of memory" after it's stopped.

I just tested again and discovered that the same happens if I open as a regular tab (+500%CPU usage).

I opened the web version on Safari and the usage is regular/very low (screenshot), so it looks like it's an Opera-related question.

If you are still having the issue, try restarting Opera.

@leocg not work， cant reinstall it 。Failed to reinstall

Edit: I've discovered this strange occurrence tends to happen when a new video begins when youtube is in the pop-up video mode. The videos will be fine if they're just in the tab, within the full frame, but if a new video starts and it's in pop-up mode, it'll simply freak out when I return to normal framing.

@burnout426 thank you so much, the new update fixed the issue

@leocg OperaGx

@leocg Fixed! Thanks!:3

@leocg I've done so and will see if they help tomorrow, thanks. Will update later.

For those that find this when searching for themselves

Go to the easy setup button on the top right of the browser.

Scroll down to RGX

untick the boxes saying Split preview for video and image enhance and the yellow line will disappear.

If you look at the pictures or videos, the yellow line starts in the middle, the left is when the browser uses RGX to enhance the image or video and the right is when it is not enhanced. So you can choose which looks best for yourself and enable or disable RGX or use the slider to increase and decrease its affect according to your personal preference.
