Problem with black artifacts on Windows 10 after installing/trying Ubuntu 20.04/18.04

Asked by Piotr

Hi Ubuntu Community,

I have problem with my two PC's. They have exactly the same problem. In first PC I had Windows 10 installed then I wanted to try something new and I installed Ubuntu 18.04.5. When I wanted to move back to Windows 10 I noticed that I have black artifacts when I minimalize windows (for example from Microsoft Edge, or device manager) and next maximalize. These artifacts also are visible when I go to Full Screen for window for example for Microsoft Edge.

It is very interesting because I test Ubuntu Linux but in version 20.04 on second PC but I didn't installed it, only live session (live USB) and I have this same artifacts now on this PC in Windows 7. When I did this live session I had unistalled hard drive and dvd drive from my motherboard. This must be problem with buggy firmware of GPU after trying linux I think. Why linux kernel or ubuntu software change some in firmware? In my opinion this is not normal and this must be bug with linux kernel.

I tried unistall AMD graphic driver in Windows 10 and I used microsoft basic driver but this doesn't change anything.

Of course .iso with Ubuntu system was checked by GPG and checksums so this can not be corrupted.

Anyone have idea what happens? Both PC have another graphic card. First have AMD GPU (HD 4200), second had Intel G31 GPU on the chipset.

Can you help me?

Ubuntu doesn't touch any firmware in Windows. It will only use the hardware. Nothing more.
Do you have the latest BIOS in the system as well as on your video card?

Did you overclock your GPU at all?

Can you help with this problem?
