Some buttons from QStyle::StandardPixmap have artifacts in the background in the dark mode

MacOS 14.3

Qt Creator 12.0.1

Steps to reproduce:

1. Build and run any example that uses one of the mentioned buttons, e.g.: https://doc.qt.io/qt-6/qtmultimedia-player-example.html 
2. Check the buttons.

Expected: The buttons should not have any artifacts. They should look like on previous Qt versions.

Actual: The buttons have some artifacts in the dark mode. Affected buttons:

QStyle::SP_MediaPlay
QStyle::SP_MediaPause
QStyle::SP_MediaSkipForward
QStyle::SP_MediaSkipBackward
QStyle::SP_MediaSeekForward
QStyle::SP_MediaSeekBackward
 

Reproducibility:  100% 
 

NOTE: The issue is not reproducible when the example is built with Qt 6.6.1 - the buttons look well there. See the attached screenshot.
