Screenshot!!!
BTW, while investigating this bug I found yet another issue. Struts are messed up when running plasma with PLASMA_USE_QT_SCALING=1.
Most likely, plasmashell needs fixing.
Git commit 67b2746ecdfd4c343db9d3fca088ae86d80a57f0 by Vlad Zagorodniy. Committed on 15/05/2019 at 08:07. Pushed by vladz into branch 'master'. Compute correct boundaries in checkWorkspacePosition Summary: When a client sets a strut, checkWorkspacePosition will be called to bump clients that touch corresponding screen edge. In order to do that, checkWorkspacePosition needs to calculate client boundaries before and after the restricted move area was changed. As it turns out, if the client reserves space "between" screens, calculated boundaries can be incorrect, which may lead to some funky results, e.g. shrunken clients. For example, let's say that there is a dual-monitor setup. If a client reserves some amount of space at the right border of the left screen, then clients on the right monitor will have rightMax which is equal to the x coordinate of screenArea. To fix that, this change ensures that only restricted areas belonging to the same screen as the client are taken into account when computing the boundaries.

Hi there, I have a dual monitor setup where the monitors are placed above each other (laptop monitor below external screen - see xrandr -q output below). If I now create a new taskbar and place it to the bottom corner of the upper screen, all the windows on the lower monitor are shrunk vertically while their horizontal size remains the same (see attached pictures). Same thing happens when moving an existing taskbar (which is set to "always visible") to this position. As soon as I move this taskbar to any other place, the windows resize back to their initial size. The bug also appears when switching from any task bar visibility mode to "always visible" and the windows also resize back to normal when switching back to another visibility mode. So I guess it has something to do with the visibility setting "always visible". The bug doesn't happen if another visibility mode is used. STEPS TO REPRODUCE 1. Setup two monitors vertically 2. Open any window and place it on the lower screen 3. Do one of the following: - Create a taskbar at the bottom edge of the upper monitor - Move an existing taskbar (which is set to "always visible") from somewhere to the bottom edge of the upper monitor - Switch the visibility mode of an existing taskbar located at the bottom edge of the uppor monitor to the visibility mode "always visible" 4. Click at any free space on the desktop to apply the changes OBSERVED RESULT Windows in lower screen shrink vertically. EXPECTED RESULT The size of all windows should remain untouched.
