Raspberry Pi 4B+ testing

[Brandon Nielsen]

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 am not seeing that on my RPi 400 (which is a Pi 4B+ under the hood,
as I understand it). It looks the same on either HDMI port so far as I
can tell.
