Chrome lags when I open 2 windows (instances) or more

I'm running ubuntu 20.04

Chrome works fine when I open just one window (instance) of it. But it lags when I open 2 windows (instances), especially If I'm using youtube or playing some videos on 1 instance.

Chrome version is 86.0.4240.75 (Official Build) (64-bit)

Note: This problem wasn't occurring before updating to ubuntu 20.04. Also, it works fine when I resize the window (not maximize)

Try disabling hardware acceleration.
