"Show On-Screen Display When Switching" option results in the on-screen display presenting on different monitors in a multi-monitor setup.

STEPS TO REPRODUCE
1. Set "Show on-screen display when switching:" to true, default duration
2. Create 3 Virtual Desktops in 3 Rows
3. Switch between them using keyboard shortcut

OBSERVED RESULT
The on-screen display appears on a different monitor depending on direction of travel, start and end point

EXPECTED RESULT
The on-screen display should appear only on the Primary Monitor

That osd is placed on the active output. In 5.18, the active output is the output that has an active window, but in later plasma versions, the active output is an output that has pointer.

It could make sense to show it in the primary output now that we have it, this way it will always show in the same output.
