Raspbian OS uses LXDE as opposed to XFCE so that could be the difference. I can say that I thought latency was better when running with a Raspbian OS on my RP-400. Or there could be other factors at play.
I built a successful non-rt kernel based on 6.1.y and now building a realtime one with 6.1.59 rt patch, patch went with no issues, so that's a good sign.
It's all fun & games so far.
I didn't try the your image rod but notice in the kernel package there was no rp5 dtb file so just assumed it would be a non starter, plus it was 1:00am and the dog was looking at me funny, like it was time for bed.

Update to above, rt kernel built & running. Happy with basic latency test, have sound, BT & wifi disabled. Haven't really pushed it nor isolated any cores. Board is 4GB as new stock of 8GB had no ETA.

Seems like some GladeVCP widgets are not working on Bookworm yet as Wayland is used instead of X11. Gremlin is throwing errors and some others like Actions are not able to initiate.
Gremlin, none of the HAL Actions and some others are not available in the Glade widgets list.
Has anybody else encountered some issues with the GladeVCP widgets as well?

The reason all of my images and ISO's run XFCE is that it is an X11 environment. There is a way to tell Wayland how to deal with X11 via an environment variable but I can't remember how.
I have no idea if this will work or not, but could you please try this Pi5 image I have just built using the same environment as we used for the official pi4b image on the Linuxcnc downloads page. It uses XFCE.

The other problem child I have encounted in the past was VTK was missing in the Raspberry repos but I see now it is available in Debian. It was a 5 hour compile on a pi4b. (Maybe that was for QTPYVCP who don't offer pi packages in their repo.)

Debian has some info here.
wiki.debian.org/Wayland#Xwayland
Or if you start with raspios lite (no desktop) and install xfce as the desktop enviroment.
or.. as per help.realvnc.com/hc/en-us/articles/14110...-and-RealVNC-Connect
Raspberry Pi 4-5: This device defaults to using Wayland (wayfire) on Pi OS Bookworm, however it is possible to switch to X11 by using the command line raspi-config utility, under Advanced Options -> Wayland. Our initial testing indicates that RealVNC Connect functions as expected in this mode.

The method is buried in comments in a commit or issue in linuxcnc's git
I'll wait patiently for my image to be tested. .....

Thanks Rod, you pointed me in the right direction and there was an easy fix
here
. Sorry I don't have Pi 5 yet to test your image.

New here.... my Pi4 1GB (yes, it exists! ) isn't good enough, my Pi5 4GB will be here soon. I'll test your images!

ATM I can't quite get SPI working, I think I may have a solution but will need to do some testing.
Just wondering if anyone else has found this to be an issue ?
This may affect 7i90, 7c80 and 7c81 boards.
Mesaflash seems to have an issue as well.
So far I've had no input from anyone on this issue.
