So I just got Kali Linux, and everything seems to run fine. Everything is smooth, all commands i use are fine, going on the internet is great, but...

I decided to try going on YouTube. Everything seems great, I can run any resolution fine without any lag, but the second I put it on fullscreen, the fps DROPS to 3 or something.

Is there a fix for this? I'm currently using Mozilla Firefox, and I am not using a virtual machine.

Thanks for the help
