Problem: Struggling with 5 inch HDMI touch screen
#1
I've been struggling now for a week with my 5 inch touch screen with HDMI. 
I'm using it with the RPi Zero W2

It is the touch screen as described here:
http://www.lcdwiki.com/res/MPI5001/EN/5i...)-V1.1.pdf

Observed behavior with 8.x.x:
Boot: goes to super high resolution. Text is small and unreadable.
When MoOde is active: display is switching on/off, sometimes completely white
When changing config.txt as described above: Boot is in 800x480, but display switches to higher resolution for MoOde GUI. Touch screen and RPi become very slow. 
When running the MPI5001-show script: RPi becomes totally unusable, MoOde doesn't seem to start and the RPi seems to enter a rebooting loop.
I've also tried a whole lot of stuff I found searching for the issue, but to no avail.

I thought it was maybe my charger, or the RPi/display being dodgy, but when I booted with just Vanilla RPi Bookworm (no changes to config.txt, or anything else), everything is fine:
Boot starts in 800x480
Desktop starts and works responsively in 800x480.

So, I was happy to see that MoOde was released this week with Bookworm. However, it still doesn't work for me out of the box:
Boot: starts at very high resolution, than changes to 800x480
SSH and browser work great.
Enabling the display makes the RPi hang -> SSH and browser can't acess the RPi anymore. Rebooting results in same behavior.

I haven't tried changing the config.txt yet or running the MPI5001 script yet on MoOde 9.0.0, but I'm a bit pessimistic it will help. 
Is there maybe anyone else that has MoOde running with this exact display, or has any clues how I best can start solving the issue?
