Running the GitHub - nerves-web-kiosk/kiosk_demo: Nerves web kiosk demo · GitHub
with {:kiosk_system_rpi5, "~> 0.2.1", runtime: false, targets: :rpi5}
RPI CM5 4GB RAM eMMC
I use the Waveshare CM5-PoE-BASE-A
I tested with an 7.0 inch HDMI Display_A05 (on the picture)
and a 2.5 K portable display
and my 4K LG 27 " Monitor
The rendering is wrong on all of them.
If Weston is killed, the iex shell looks normal.
Startup logs with 7 inch:
The ideal resolution for the 7 inch would be 1024×600 and 30 frames would be enough if you know how to enforce that, I would appreciate a hint 
Since I can not upload the picture here, take a look on the GitHub Issue:

Added my suggestion for how to configure weston in the issue: CM5 boot loop · Issue #8 · nerves-web-kiosk/kiosk_demo · GitHub

Following up on this since the root cause of this issue has been addressed by updating Mesa3D to include fixes for the RPi5. The
kiosk_exampleapp should work now.
