RaspberryPi 4 with Trixie X Wayland question

I am setting up a RaspberryPi4 with 4 Mb RAM to run OpenCV. It will be running on an isolated safe LAN headless.

I am using Vinagre VNC client on a number of computers to access a number of other headless RPi’s.

The new RPi O/S, Trixie defaults to Wayland. I cannot access the new RPi via VNC because Vinagre and Wayland do not play together and I am not going to RealVNC because 1) something new to fight with and 2) it requires cloud connection which will not be available on my isolated LAN.

So, if I ditch the Wayland and go back to X on the RPi so that I can use an X based display manager will I run into problems with OpenCV?

not with OpenCV, as long as you stay away from GUI entirely or else whatever GUI libraries there are will work properly.
