[fedora-arm] Fedora 33 update problem

[Alan]

I have a new Rasberry Pi 4b with 8gigs of ram. I installed the Fedora
33 1.3 image. Everything installs ok. Reboots fine. No problems.

If I update using dnf, video no longer works. (I get a corrupted
screen.) 

Is this a known issue?

Also the verify file on the web site is for the 1.2 image, not the 1.3
image.
