Created attachment 1956391 [details] captured selected system calls of xdg-desktop-portal-gnome for aronud 10 seconds showing the queries to cupsd and responses Description of problem: After the system is running a while (unclear, i would say, a few hours) xdg-desktop-portal-gnome starts to permanently query cups, about 27 times per second. Thus both xdg-desktop-portal-gnome and cupsd have a CPU utilization of 6-8%. No print job is active, nothing in any queue. Version-Release number of selected component (if applicable): xdg-desktop-portal-gnome-43.1-1.fc37.x86_64 How reproducible: Steps to Reproduce: 1. Start up the system. 2. Wait for a while Actual results: as described above. Expected results: anyone and anything may query cups, but not 27 times per second for no obvious reason.
