--- Comment #3 from Zdeněk Válek <zd.va...@seznam.cz> --- I was able to find the option which causes this unwanted behavior on my setup. It is in kwin configuration file kwinrc: [Windows] HideUtilityWindowsForInactive=false When set to false, all hidden panels appear whenever I switch active window and the panels remain visible until I manualy hide them with mouse. When set to true, the panels are OK. I think this behavior shall be fixed. I don't know what the option is for and how it got into my configuration, but IMHO it should not affect the panels this way. Maybe the Product shall be changed to kwin, but it affects panel, so I am not sure with that. My kwin is 5.14.5 -- You are receiving this mail because: You are watching all bug changes.
