Popup menu not displayed with QT 6.8.3 and QT 6.9

Hi,

kColorPicker works fine with Qt 6.7.3 compiled with kdesrc-build script: the popup allowing to select a color is shown.
With QT 6.8.3 and QT 6.9, the popup is not displayed.
Nothing happens when clicking on the square button.
QT 6.8.3 was built with kdrsrc-build script.
QT 6.9 was installed with QT installer.
I have the same behavior with both ksnip and example/kColorPicker-example.

Thanks!

Tried again with latest Qt 6.9.2: works fine again.
So this seems to be a Qt problem, not a kColorPicker one.
