Video/Streams on second monitor lagging when Opera isn't in focus.

This video shows the issue I'm facing.

Whenever I am playing a game, and Opera is not focused, videos and streams lag a LOT. Sometimes, however, this issue doesn't occur, so I am un-aware what could be causing this.

I've tried disabling hardware acceleration, switched to OpenGL. Nothing has worked.

My PC specs are as follows:

Windows OS
AMD Ryzen 9 3900X 12 core
AMD Radeon RX 5700 XT
16 GB Memory
650W psu (I do not believe a lack of power is the issue)
