I'll see what I can do. I will mention that since these are very new there is surely growing pains. Be careful to test things.

What are some of the system requirements for using these new Qt screens? Are there a lot of dependencies to install? What are the minimum screen resolution/sizes?

I'm often frustrated by the fact that most of the new GUIs developed won't even fit on a 1024x768 screen and heaven forbid if your stuck with 640x480.

here are the libraries neede for displaying the screens:
need for displayimg pyqt widgets:
python-pyqt5
python-pyqt5.qsci
python.pyqt5.qtopengl
python-pyqt5.qtsvg
python-opengl
python-opencv

optional:
espeak
espeak-ng-espeak
python-dbus.mainloop.pyqt

To build build/modify screens requires a couple more libraries and copying a file, details here:
github.com/LinuxCNC/linuxcnc/blob/master.../designer/README.txt

Minimum screen resolution varies:
QtDragon 1440x860 - not resizable
QtAxis 508x 600 resizeable
Default 1027x790 non resixeable
QtX1mill 1024x768 non resizable
Qttouchy 833x705 resizeable

Screens can be styled too, here is touchy with and without a styled theme added:





I also added graphics to it:


Most of these screens were built to exercise qtvcp's features for testing.
I'm sure people can come up with better ones (like QtDragon)

I understand that the opengl for the qt5 screens failed on RPI4 - I don't have one to test with and am not an opengl expert. Not sure if it is just a library change required or something else.

I have a new and improved version of QtDragon. It's not just a sample screen, but a fully functional GUI for 3 or 4 axes, VFD control, and probing. If you are interested in updating the current one, I will put together a package.
