SUMMARY When using multiple KDE desktop widgets on a secondary screen, their positions often get scrambled after a system restart. Manually repositioning them causes a bug where all desktop notifications start appearing at the top left corner of the secondary screen. This issue can only be resolved by restarting, but the widgets' positions get scrambled again. STEPS TO REPRODUCE 1. Place multiple KDE desktop widgets on a secondary screen. 2. Restart the system. 3. Notice the widgets' positions have changed. 4. Manually reposition the widgets. 5. Observe that all desktop notifications now appear at the top left corner of the secondary screen. OBSERVED RESULT After restarting, the positions of the widgets on the secondary screen become scrambled. Manually adjusting the positions causes a bug where all desktop notifications appear in the top left corner of the secondary screen. EXPECTED RESULT The positions of the widgets should remain consistent after a restart. Adjusting the widget positions manually should not cause any issues with the location of desktop notifications.

This should be fixed in Plasma 6.4 due to various related changes. Please feel free to re-open the bug report if you find that it's not fully fixed for you after upgrading to 6.4, though. Thanks!
