PyQt 6.8 font problem

Marko86s

Why font rendering is too bad with PyQt6.18?
Here is how looks on 6.8 and 6.7.1

@Txai
I would not assume it necessarily has anything to do with PyQt. Might be a Qt 6.8 thing.
Maybe OP can try with PySide6?

Which OS/platform and which font/size is this?

@JonB thanks but PySide6 isn't an option for me. I mean, the whole project is based on PyQt6. Something is definitely wrong there with Qt6.8 and how font is rendering.

@friedemannkleint Windows font size 12px, font family is same, all is same on both images only PyQt is different, with PyQt6.8 font looks bolder and somehow bad, I can't explain.

The idea was to test whatever you are doing that looks wrong in a two line program under PySide rather than PyQt. Then people would know whether it's a Qt or PyQt issue. Not to rewrite your application.

Looks I found problem
PyQt6.7 read font name like "JetBrainsMono NFP" and that's works fine.
For some reason in PyQt6.8 this does not work and font must set like "JetBrainsMono Nerd Font Propo"
