I use the "Qt5 Configuration Tool", which I think you can install in Debian, to adjust the font size and collection folder icon theme. Perhaps that's something you could try.
I am using Linux Mint and the tool works well for tweaking non-GTK apps.

I dont know what this playing widget feature is, as I see no difference (even while playing) no matter if its activated or not, but even with it deactivated adding the PlayingWidget section and setting the above_status_bar key in strawberry.conf stretches the seekbar to the whole width as desired, so many thanks for your hint.
Possible reasons songs are not picked up could be hidden folders, incorrect permissions or unsupported audio format.
Check and see if there are some differences between those that are not picked up and those that appear in the collection.
When you find a file that is not in the collection try dragging the file from finder to the playlist window and see if you get an error message.
It calculates and stores a unique fingerprint for each song in the database so that if the files are renamed or moved on disk (within the collection directory) it manage to track where the files moves so it does not loose playcounts and ratings data.

No, strawberry does not set icon for filetypes. Icons for mimetypes are loaded from /usr/share/icons/ there is usually subfolders called mimetypes.
@jonas I realize I'm replying to an old post, but I didn't see any reason to make a new one. I would like to revisit this issue of the wrong bit depth being reported by GStreamer when an aac file is playing (32 bits instead of 16 bits). Where can I report this to the GStreamer developers? Or is it something you can report? I have GitHub and GitLab accounts, but I am just a Linux hobbyist. I report bugs, but I don't have the deep technical knowledge that would enhance my reporting. Thanks.
