This is ultimately an upstream bug, I've filed https://bugreports.qt.io/browse/QTBUG-125867 for it. However, I've also found a fairly simple workaround so I'll make a merge request for that as well. A possibly relevant merge request was started @ https://invent.kde.org/plasma/plasma-systemmonitor/-/merge_requests/338 Git commit 8d6f9db638fc1dfb8a2f7fc9bb1bb9007698b68e by David Redondo. Committed on 30/01/2025 at 14:03. Pushed by davidre into branch 'master'. Set interactive of TableView and page flickable to false SelectionRectangle has a weird interaction where it can intercept mouse events when it shouldn't (QTBUG-125867) for some reason setting the flickables to not be interactive works around this. This should have no other effect because we are in scrollviews that manage touch and scrolling.

Created attachment 169607 [details] Screenshot showing the background moving when dragging an item in the foreground SUMMARY Drag events are captured by the underlying process list in 'Configure columns...' when the drag handles fall above the process list table instead of overlapping the sidebar. STEPS TO REPRODUCE 1. Open System Monitor. 2. Maximize the window. 3. Switch to the 'Processes' pane. 4. Click 'Configure columns...' in the toolbar. 5. Try to drag an item in the list to change the order. OBSERVED RESULT The table in the background moves instead of the item that is being dragged. It is not possible to drag the items in the foreground. EXPECTED RESULT The item in the foreground would move when dragging by its drag handle. SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Plasma Version: 6.0.4 KDE Frameworks Version: 6.2.0 Qt Version: 6.7.0 ADDITIONAL INFORMATION This appears to happen when the drag handles in the foreground list sit above the process table in the background. When initially opening the window, the drag handles are usually placed just slightly overlapping the sidebar, which allows them to be dragged. When maximizing the window or making it wider, they no longer sit above the sidebar and the drag events are captured by the table in the background.
