Bug Description

This is a long time problem in Qt on macOS: When scrolling the library up and down continuously, CPU usage goes to 99 %:

100 % reproducible.

macOS 13.6.5
Mixxx 2.5-alpha-255-g2d2d5f304b (main)
Qt 6.5.3

This is not a new problem, it has been going on for as long Mixxx was available on macOS. This needs to be resolved in Qt, but it is fair to have this issue in the Mixxx repo, to keep track of things.
