HiFiBerryOS: imagemagick & oom killer

I recently installed HiFiBerryOS on a 1GB RPi 4. It has been a bit unreliable - music skipping occasionally, and significant lag controlling mpd (over wifi, but with a decent signal). All music is stored locally on the microSD card, so playback shouldn't be affected by the network connection.

In the process of troubleshooting, I noticed that oom killer is killing imagemagick convert processes every couple of minutes. From dmesg:

[Fri Oct 28 22:13:49 2022] Out of memory: Killed process 13115 (convert) total-vm:442584kB, anon-rss:407644kB, file-rss:0kB, shmem-rss:0kB, UID:0 pgtables:872kB oom_score_adj:0

Is this normal behavior, or should I submit a bug? Each killed process using ~400MB of RSS memory, which sounds unreasonably high.

I assume imagemagick is being used to process album art - is there a way I can disable album art entirely? I have already disabled downloading album covers from the internet, but it hasn't fixed the problem.
