SUMMARY I noticed that Discover had begun taking a very long time (multiple minutes) to open after installing the Kubuntu Beta Builds ppa. Starting Discover with strace I was able to see that it appears to be attempting to enumerate the contents of my OneDrive that I had mounted using rclone. STEPS TO REPRODUCE 1. Configure rclone to mount a personal OneDrive share with a sufficient number of files (I believe it is the number of the directories/files to traverse that is the problem, hopefully Discover isn't actually looking at the contents of these files) 2. Open Discover 3. Wait a long time OBSERVED RESULT Eventually Discover will open and then it works normally EXPECTED RESULT Discover opens quickly SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kubuntu 25.04 KDE Plasma Version: 6.4.3 KDE Frameworks Version: 6,14,9 Qt Version: 6.8.3 ADDITIONAL INFORMATION rclone version 1.60.1-DEV I'm not certain if the problem is tied to the frontend or a particular backend.
Can you give us some clues what files it's accessing.
It just appears to be scanning the whole folder alphabetically.

Nothing obvious sticks out. Can you maybe attach gdb and try to catch a backtrace for the openat call? It's possibly some library causing this, but we'll probably need to catch it in the act.
I would need some detailed instructions to provide that information.

Since I didn't receive instructions on how to provide additional information, I've adjusted my setup to mount the share under /media/[username]/OneDrive instead. This resolves my problem, nevertheless, under Kubuntu at least, it appears to me that Discover scans the files in the user's home directory at startup for some unknown reason.
