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. Additional info: Find attached selected system calls captured with strace including timestamps for around 10 seconds top shows: top - 20:45:16 up 1 day, 8:33, 3 users, load average: 0.42, 0.76, 0.82 Tasks: 232 total, 3 running, 229 sleeping, 0 stopped, 0 zombie %Cpu(s): 5.5 us, 6.2 sy, 0.0 ni, 88.2 id, 0.0 wa, 0.0 hi, 0.2 si, 0.0 st MiB Mem : 5550.4 total, 785.1 free, 2007.4 used, 2758.0 buff/cache MiB Swap: 9646.0 total, 9644.9 free, 1.1 used. 2925.2 avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3227 user1 20 0 1471804 145428 72136 S 8.3 2.6 15:45.45 xdg-deskt+ 977 root 20 0 248408 12224 8776 R 7.3 0.2 13:25.87 cupsd I can't accept such useless waste of CPU resources.
