3B+ & 7" Touch screen, with Moode 9.1.4.

Does the update log show a successful completion?

Code:

moodeutl --updlog

Looks like it, it got all the way through to “Update installed, restart needed”

I even power cycled for a cold reboot.

Most likely a stale chromium browser cache. Try restarting Local display from Peripheral Config. This will clear the cache.

But just as an FYI the changes in the videocore driver introduced with Bookworm heavily favor the video chip hardware and HDMI interface on the pi4 and pi5. This is because one of their goals is to have a first-class Desktop.

For me a Pi3 and 7" Touch is almost unusable as compared to a 10" HDMI touch with a pi4 which is very good.

There are some hacks in moode for dealing with some platform audio and video issues for example "Disable GPU" and "Firmware mode (Legacy)" but these are just best effort.
