I'm having an issue with high usage by Opera recently. 6 tabs opened, 2 active - 4GB of ram and 37% of CPU constantly.
Tried the internal task manager - it's all caused by the tab with Youtube video - it uses over 3GBs and is responsible for 80% of CPU usage of the Opera. I'm watching the video in 720p so it's not even something super high.
I started noticing this behavior few days ago.
My video card drivers are up to date.
What can I do about it?

When I click on the notifications button, the menu takes up to 8s to load, even if there's few items there. Also sometimes the video playback stops and I need to reload the page.
I'm not experiencing such issues on other sites. Weird.
