[RESOLVED] Qbittorrent high idle CPU usage after 5.2.0 upgrade

Mostly looking for advice on figuring out whether the problem is with the package, or upstream.

After doing a system upgrade, the current version has the processed pegged at 100% CPU usage when idle.

Downgrading the package to version 5.1.4-2, the issue does not persist.

Running a strace, I see this spammed in the output:

ppoll([{fd=5, events=POLLIN}, {fd=15, events=POLLIN}, {fd=91, events=POLLIN}, {fd=102, events=POLLIN}], 4, {tv_sec=0, tv_nsec=0}, NULL, 8) = 0 (Timeout)

Yup looks like that was it. Seems the search terms I used didn't bring that one up.

Thanks!

Did you test the patch?

If so and in case please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

I have not tested a patch, however the cause is related to RSS feed reading, which I have turned off, which resolved the issue.

(I also didn't realize I could edit my own post title after the fact)
