SUMMARY Right clicking an item in the applications or processes lists results in the context menu appearing offset right and down from the cursor, by an amount that seems to be equivalent to the width of the sidebar, i.e. collapsing the sidebar makes this distance smaller. STEPS TO REPRODUCE 1. Open System Monitor 2. Right click in application item in any of the process lists 3. Notice menu offset OBSERVED RESULT Menu is offset EXPECTED RESULT Menu is aligned to the cursor SOFTWARE/OS VERSIONS Linux: Arch KDE Plasma Version: 6.3.4 KDE Frameworks Version: 6.13.0 Qt Version: 6.9.0 ADDITIONAL INFORMATION The way this context menu is implemented is unconventional, it should ideally be a window or a "native" menu, not a widget inside the main window. The whole experience with system monitor is bad to be honest, one of the most unstable components of Plasma.
