Solved > Weird glitches on Youtube videos

[FLRIZDARKK]

I got working my ASUS Vivobook S15 Hackintosh recently and all going well. The only problem that I'm facing is some weird glitches while playing YouTube videos only on 1080p and only on fullscreen. The glitches are randomly a part of the video turns grey for just a frame, then its normal, then again the same glitch. My system info is displaying my iGPU correctly (UHD 620) with the normal VRAM. What should I try?

CPU: i7-8550u

RAM: 8GB DDR4 2400Mhz

GPU: UHD 620

OS: 10.15.6

Browser: Safari (720p works fine mind you in fullscreen, and 1080p not in fullscreen also work fine).
