SUMMARY
When multiple tasks are on my replicated display that happens to be replicated by another, clicking on the grouped task shows no windows all but one of the replicated displays, including the 'source' display. It seems that the display index dictates which display the window previews are displayed on. Disabling the replication allows the task manager to function normally again.

STEPS TO REPRODUCE
1. Use Icon-Only Task Manager on primary monitor
2. Setup a secondary (or even tertiary) monitor that are replications of the primary
3. Open multiple windows of the same application
4. Click on grouped task in task manager

OBSERVED RESULT
Window previews are shown on just one display

EXPECTED RESULT
Window previews are shown on all displays

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: kernel 6.11.2
KDE Plasma Version: 6.1.5
KDE Frameworks Version: 6.6.0
Qt Version: 6.7.2

ADDITIONAL INFORMATION
Using Nvidia on Wayland, may be a factor but I'm not 100% sure of it.

Ultimately this is caused by Bug 481222.
