I wanted to say, that with the same fractional settings widgets are bigger on Wayland, which shouldn't happen.

You can see that on Wayland these widgets reach a lot lower than on X.org.
Comment 5 David Edmundson 2020-05-01 21:13:43 UTC 
Where is this coming from?

QT_DEVICE_PIXEL_RATIO=auto

that's not us.
Comment 6 Lucia Mrenica 2020-05-02 07:43:55 UTC 
QT_DEVICE_PIXEL_RATIO=auto was set by packettracer package, but removing it didn't make any difference. I also tested this on Kde Neon live and it is also present there.
Comment 7 Nate Graham 2021-01-08 21:05:25 UTC 
I believe this is expected due to differences in default scaling methods on X11 and Wayland. It's yet another example of Bug 356446.
