PySide 6.10.0-6.10.1 upgrade changed my padding on Windows, how to restore?

I'm not too familiar with Qt, I inherited this project.

This problem only exists on Windows, macOS/Linux is fine. If I use 6.10.0 or earlier, it looks how I expect:

But if I go to pyside 6.10.1 or later, including 6.12, it looks like this:

This is the project, in case it's useful: https://github.com/ciromattia/kcc

The app also builds using 6.1.3 and 6.4.3 for legacy OS. So hopefully any change doesn't affect the older pyside. the app was on pyqt5 originally but I ported to pyside6.

This is mainly because I want to use python 3.14 but that needs 6.10.1

Could you maybe specify which UI elements and differences you mean specifically?

Christian Ehrlicher

This was due to the non-fully ready win11 style in Qt6.10 - in 6.12 the margins are adopted to match more to the winui3 style

I still have the problem of extra padding around the check boxes and the top messages in 6.12.0.

I probably can override this manually but I feel I shouldn't have to.

changing the setStyle() between windows11, windowsvista, Windows, and Fusion has varying results.

Just for reference, here's what it looks on macOS: https://forum.qt.io/topic/165221/pyside6-ui-looks-different-depending-on-which-macos-built-python

I actually took a little more time and started comparing screenshots side by side.

The padding for default theme changed in 6.10.1 and is still the same in 6.12.

I think this is probably intentional and I shouldn't expect help.

However, closer inspection of the windowsvista theme does have the original spacing, so I think I'll just use that when I upgrade Qt. It looks close enough I suppose. The app is from 2012 so I guess an old look is fine. I really prefer the 6.9 look but that's just a nitpick.

Maybe I could request the 6.9 theme somehow? idk, what would it even be called, windows10?

this is the vista theme:
