Public bug reported:

Since Ubuntu switched to Gnome, display scaling does not work correctly.
This is because my external monitor is detected as 7" although it is
32". All applications which use Qt auto scaling have huge controls!

It seems like many users have the same problem
(https://ubuntuforums.org/showthread.php?t=2390362) and thus disable Qt
auto scaling. I think the solution should be to fix the size detection
instead.

Further, it seems not related to graphics driver, since I personally use
the open source driver with my internal Intel card, whereas someone else
uses a proprietary Nvidia driver
(https://askubuntu.com/q/1066879/206608).

If it is in the wrong category, please move it / add the corresponding
packages.

If you need any further information to tackle the problem, just tell me!
