We have an CM5 installed originally from this image: 2024-11-19-raspios-bookworm-arm64-lite.img
We can then run the SDL EGL demo perfectly by doing the following after flashing the above image...
... we see the spinning colored cube on the TV attached to HDMI0.
Then if we do a standard:-
to get the latest updates since the original image, and reboot, running the above testgl2 results in a corrupt picture output (random pixels over the entire screen).
The above sequence was working back in February this year, so I guess some package update recently (the last month or so) has broken something.
A normal Rpi5 works fine, so looks CM5 specific.
Can anyone else reproduce or advise me on how best to attempt to track down the specific package update which might have caused this?
