SUMMARY Before Plasma 6.3.4, everything was fine, but since I updated to Plasma 6.3.4, the activity switcher is not showing itself on my principal screen anymore, it shows itself only on my secondary screen. Clicking on the widget in the panel of my principal screen does not show activity switcher sidebar at all (not on primary screen, not on secondary screen). Clicking on the widget in the panel of my secondary screen does show activity switcher sidebar on the secondary screen as intended. I noticed something strange when I have a window on the principal screen and clicking on the widget in the panel, it seems that the window loose its focus (shadow is reduced), so I think that activity switcher sidebar is « appearing » somewhere out of both screen, then if I click again on the widget in the panel, it seems that the window take again its focus (shadow is back). STEPS TO REPRODUCE 1. Update to 6.3.4 2. Play with activity switcher sidebar in a multimonitor context OBSERVED RESULT Activity switcher sidebar is not showing at all on principal screen. EXPECTED RESULT Activity switcher sidebar is showing on principal screen.

Very likely caused by the fix for Bug 480890. It affects the Add Widgets sidebar too, right?

Do you mean when I right click on panel from principal screen, for example? If it’s that, nope, it works correctly, the add widget sidebar is available on the principal screen, without any issue.

But as the change in the commit of that bug is small and just QML I simply tried to revert the changes in my local Desktop.qml and it fixed the problem. So yes, it is caused by that fix.

Do i need to do a new bug report or it's a duplicate in advance of this issue? https://discuss.kde.org/t/activity-selector-panel-misaligned-no-longer-left-anchored-after-update-kde-neon-wayland/32641
Hmm, the symptoms are different. It may be a different issue.

Just applied a revert of the commit, I confirm too that it fixes this regression.

Git commit 515af63832d9c16b8f440b0d6880787bd9c5f761 by Niccolò Venerandi. Committed on 14/04/2025 at 18:10. Pushed by niccolove into branch 'Plasma/6.3'. Avoid double-addition of x coordinate of ActivitySwitcher The current code was adding the x coordinate of the screen geometry two times, in the screenGeometry variable and in the code to calculate the x coordinate.
