You could try it with switching to Xorg to see if it behaves different. To switch, go to the Login Screen. Click there on Your Profile so that the Passowrd Field appears. When it is appeared, You should see a Gear Icon in the bottom right Corner. Click on it and choose the Option ''Zorin Desktop on Xorg'' and then log in and see if it helps.
Another Thing: You could take a Look in Your BIOS to disable the iGPU or use the AMD Graphics as primary Graphics Output. Unfortunately there isn't unified how the Options are called or where to find them. So, you would have to search a bit.
