HiDPI + Wayland + Spyder 6: bad window size in preferences

[Firestar-Reimu]

You can see that the font of Syntax Highlighting is cut by the window, and the window for previewing is also too small

the line height can be adjusted by dragging the window border but the window of Appearance cannot be bigger

I have tested on Screen Resolution of Normal/Enable Auto HiDPI/Manual Scaling

In fact Spyder 5 looks worse, small icons on big icon boxes, the left menu of preferences is also bad

As a workaround you can try to run spyder like this : QT_AUTO_SCREEN_SCALE_FACTOR=1 spyder.
For me it solved the issue you described with Spyder 5.

Hey @Firestar-Reimu, thanks for reporting. Could you try @majneb workaround and let us if it works for you?

OK on Spyder 6, the icons looks a lot bigger, but the preferences window looks better (although it fills the entire screen)

Notebook also seems fine:

BUT after I turn it off and re-open spyder, I cannot start with spyder or it will stuck:

Only I start it with QT_AUTO_SCREEN_SCALE_FACTOR=1 spyder every time will it load swiftly

Sorry for the late reply @Firestar-Reimu. You said:

That's the way we designed the interface, so there's no problem with that.

BUT after I turn it off and re-open spyder, I cannot start with spyder or it will stuck

We'll try to fix that in a future version, but I think running spyder --reset in a terminal should solve that problem.
