[fedora-arm] Re: Raspberry Pi 4B+ testing

Hi all,

I just noticed on my Pi 4B+ that display output on the second micro HDMI
port (the one further from the USB-C power supply port) is corrupted.
The first port is fine.

The corruption is visible as rainbow halos around text during boot, and
increasingly large areas of corruption after booting to a graphical
desktop (green dots, color shifts, etc.).

I can confirm this with the Fedora 41 1.3 RCs for both KDE and Workstation.

Has anyone else seen this? I'm trying to rule out it just being a
hardware fault with my unit.

I can confirm that, and thank you very much.
I had pulled an old monitor off a shelf to test and thought I was having monitor problems.
I read your email, switched display ports on my rpi4b, and now it's working.
