Created attachment 175665 [details] pressing Meta+V on a multi-monitor desktop SUMMARY I am running plasma on a desktop with 4 mixed resolutions monitors. Pressing Meta+V to show the clipboard history at mouse position results in the applet's window showing in different and weird narrow geometries at times. STEPS TO REPRODUCE 1. press multiple times Meta+V to open the clipboard applet 2. 3. OBSERVED RESULT The clipboard applet will open in different geometries everytime you press Meta+V EXPECTED RESULT The clipboard applet should open always with the same and usable geometry.

When the window becomes visible the attached screen might not be the current one, which might be a bug in Qt or Wayland.
(In reply to Fushan Wen from comment #1) > When the window becomes visible the attached screen might not be the current > one, which might be a bug in Qt or Wayland. Actually I can say for sure that the same thing happens if before hitting ctrl+v I click on a window on the same screen where the clipboard history will appear, hence with the window appearing on the current active screen. It all started after upgrading to plasma 6.2. On a side note I have ActiveMouseScreen=0 set in kwinrc for the same reasons pointed here (I am also the author of that comment): https://invent.kde.org/plasma/kwin/-/merge_requests/5102#note_882547 Could it be the cause of this bug? Do I still need that option in kwinrc?
I'm not able to reproduce this on Wayland, git-master with two screens Laptop: 1920x1080@100% Monitor:3440x1440@100% In the kwinrc file on that machine this is the only value for ActiveMouseScreen: [Windows] ActiveMouseScreen[$d]

If I try disabling two of the four screens setup, the clipboard popup still opens in different geometries. 2. If I login in plasma with only two screens, then I can't reproduce this bug. The clipboard popup retains the same dimension on the two screens. 3. I noticed that if I repedetly type meta+v, on every second hit the clipboard popup closes. This randomly happens only on the first and fourth monitor. > In the kwinrc file on that machine this is the only value for > ActiveMouseScreen: > > [Windows] > ActiveMouseScreen[$d] After some more digging I don't think ActiveMouseScreen does anything anymore as each screen can now be the active one even if the mouse pointer is on another screen, by default. Removing ActiveMouseScreen from kwinrc didn't change anything.
I can reproduce it. The window doesn't always follow the current mouse cursor, so is the window size.
