That’s interesting. I never had the fuzzed multicoloured screen.
Maybe we use a different image?
I use “Fedora Minimal” from here:
Besides of bash-completion, locales, crond, wget, tar and dnsmasq, it still is very minimal without much overhead.
Since there is no desktop environment installed, I might just don’t experince all those problems.
It just serves as a dhcp and dns provider that also has a blacklist to sort out advertising and other unwanted things.
From last time I installed up to now I didn’t update the firmware.
So I still have:
rpm -qa | grep linux-firmware
I also added
Since most of the time I only connect via ssh to the pi and there is (or was?) an issue that prevents the pi from starting if there’s no monitor connected. Using ssh has the advantage that I can conveniently copy and paste. All this additional functionality is provided by the controller host with the full gnome desktop environment.
Searching for a solution for that boot problem that I finally found here I might have come across a thread mentioning a fuzzed out colour screen, but I’m not sure if I remember this correctly.
To figure a bit out what’s going on I now connected a screen to it, rebooted with kernel 5.10.23-200.fc33.aarch64, and didn’t get a fuzzed multicoloured screen.
Also after updating the kernel to 5.11.7-200.fc33.aarch64 I cant see any issues, besides of missing blueteeth, which I don’t use anyway. And this is not new. Using the Fedora Minimal image the bluetooth driver never worked for me and I had no desire to get them working. Maybe they are just missing in the firmware package?

Can you provide a screenshot of a fuzzed colour screen?
Sometimes this also can be caused by a the connector. But this might change if you slowly and gently move the cable at the micro hdmi connector slot. Be cautious since one can accidentaly do some harm there.
