Style mistake in win11 with Qt 6.7+ mingw 11.2 official online release.

[goldenhawking]

This problem is discovered first in msys2, because in msys2 qtcreator is built with Qt 6.7. At the same time , qtcreator in the offical Qt online installer is still depended on QT 6.6.

PROBLEM:

Spinbox and combo box drop list 's stylesheet not work in windows 11 .

The picture below shows that in a hello-world Qt 6.7 mingw 11.2 app, spinbox become strange:

Qtcreator in msys2 : Help page's dropdown list 's front color is very similar to background:

Start Qt app with

$ app.exe --style fusion

can fix this problem, which shows that this is indeed a style-sheet problem.

I installed a vm win11 tonight. Official Qt online installer seems to be normal, because Qt creator is built with Qt 6.6. If you compile a hello-world widgets app with Qt 6.7 mingw 11.2, this problem will happen again.

@goldenhawking said in Style mistake in win11 with MSYS2 Qt 6.7:

Spinbox and combo box drop list 's stylesheet not work in windows 11 and MSYS2 ucrt64.

What has MSys to do with this? Did you compile Qt by yourself or how is msys involved?
Do you have a high-dpi screen?

The QtCreator config directory in appData has been deleted, but that approach does not work.

@Christian-Ehrlicher

A new virtual machine with windows 11 has been established for testing.

Just install official online opensource edition with Mingw 11.2 and Qt 6.7.

1. create an empty dialog Qt C++ application.
2. drag a spinbox to ui.
3. compile and run, this problem can be visible.

While I can see that the default style has changed (spin box controls and colouring), I don't see a "mistake." This UI is usable with a light or dark theme, and consistent with colour usage elsewhere in native Windows apps.
