Hey @adpe45,
Interesting!
Please update /boot/userconfig.txt with:
[all]
display_auto_detect=1
dtoverlay=vc4-kms-v3d
dtoverlay=vc4-kms-dsi-7inch
After reboot:
List loaded modules by lsmod > lsmod.txt and attach lsmod.txt to your report.
Post link of your new bug report log with your report.
Kind Regards,
