Game causes online videos to stutter/lagging

Not sure if this is the correct category, but I’ll post it here just in case.

So basically I’ve run into a weird issue that I haven’t experienced before. The game is running smoothly on ultra and my computer should have no issues running the game. However every time I start the game, any online video I play on Chrome starts to stutter/lag, which is quite annoying. It does not affect videos on Microsoft Edge apparently and it’s running smoothly there even though I have Chrome up as well.
Any idea why this happen and a possible countermeasure?

My computers specs are as follows:
CPU: Intel Core I5 6600K Skylake
MB: MSI Z170A KRAIT GAMING, Socket 1151
RAM: 2x Corsair Vengeance LPX DDR4 2666MHz
GPU: 1x ASUS GeForce GTX 1070 ROG Strix Gaming
Disk 1 (Primary): NVMe Samsung SSD 960 (M.2)
Disk 2 (Secondary): Seagate Desktop 2TB SSHD

The game ui is just a chrome window overlay. Maybe it is related? I would think it should not affect it, but I’m not sure.

Could be. Would be nice to know if others are affected as well then.
