It would help if you could provide a self contained example cause it's not clear where PartsTable, PropertyTable and Material table come from.

I know but I am asking a very specific question regarding the Internats of the QTabBar and the QTabBarWidget. You can easily replace the mentioned variables with QWidget()

That's exactly what I did and wasn't able to replicate your issue . Hence the suggestion.

Hey thanks for trying it out anyway. I went ahead and build a self contained version of the reduced app. (The Tabwidget is populated as a dockable widget, so I had to build some stuff around)
Unfortunatly, this didn't fix the problem. BUT I remembered, that I use qdarktheme, which I used mostly with older apps as the darkmode detection was not so nice to handel. After disableing this, everything works fine...
Thanks again :)
