Yesterday I got XFX RX 580 4G from my friend. I decided to replace my GTX 1650 with it. I wiped drivers with DDU, and went to replace GPU. After replacement I turn on the PC and I was presented with these graphics glitches on splash screen (Gigabyte Logo) and in Windows itself. I continued with installing drivers hoping these glitches will be gone. And so they did. I tested battlefield 1 and CS:GO for multiple hours and I saw no problems at all. I also run Ungine Heaven Bencmark for 30 minutes and I didn't saw any problems there either. But one problem remained and that it glitches on splash screen when restarting or powering on PC. I tried resetting BIOS but it didn't help. I will attach you video and picture of those glitches. Keep in mine these only happen on splash screen (gigabyte logo), while UEFI works fine.

In this video there's no glitch on Gigabyte logo, and that's another thing to note, once you enter UEFI and reboot it won't show glitches until you turn the PC off. But this "box" will always show up. Gigabyte logo will look exactly like this desktop photo sometimes.
