How to use QtCreator with wayland?

Question

linux

Good day!
I want to ask users of QtCreator ( linux ) - how did you solve the problem with High DPI ?
QtCreator is not capable of scaling to High DPI . I found two solutions to this problem:
0. Using variables:

QT_AUTO_SCREEN_SCALE_FACTOR=0 QT_SCALE_FACTOR=1 QT_SCREEN_SCALE_FACTORS=2 ./qtcreator

1. Using wayland :
./qtcreator -platform wayland
In general, the parameters have an effect, but there is still a feeling that the IDE is not fully optimized for screen resolution. Before the launch, I still had to tweak the scale system settings for fonts, windows, elements, and other things.
I could not tune wayland - I did it according to the manuals, as a result, QtCreator did not detect wayland :

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

And after restarting the beech, I completely lost the entire GUI and had to clean up everything that I had installed over the past 24 in command line mode and reinstall gnome packages ( gdm3 , ...).
Actually, I want to ask you to attach a screenshot of QtCreator under wayland (who uses it, of course) and describe the process of installing it into the system, because the second time I don’t want to put the GUI in the axis.
I am attaching screenshots:

Run without parameters;

With options.
