I've been looking into this for months. I don't understand why vmware can do this without issue but kvm can't.

No. Force stop and then start the vm. hit esc rapidly on the bios boot logo screen to open bios settings. from there, go to device manager and change ovmf's resolution to match clover (1920x1080 default)

This is the exact problem I've been hitting with my 5700 XT: Been searching for days trying to fix it.

Just coming into this thread...is your bios resolution the same as clover? that's required. vnc back into macOS, edit clover resolution to match your monitors NATIVE resolution (under gui section). Hit esc rapidly while booting back up so you get into the OVMF menu and change target resolution to match.
