I can confirm that there is something strange in the file.
But I can't reproduce the problem from scratch in a new file.
It may be useful to inform how the file came to this state.

I don't know for sure actually. I imported the brushes (append) from another file and after a while the icons disappeared.

Can confirm.

Two first notes:

  • [1] getting an assert loading a custom icon
BLI_assert failed: source/blender/blenkernel/intern/icons.cc:762, BKE_icon_id_ensure(), at '((((*p_prv)->icon_id) == (0)) || (((*p_prv)->icon_id) == (id->icon_id)))'
  • [2] also custom icons with alpha seem to draw messy since 2.80?

Seems like this has come up before, see T71520: Custom brush icon file don´t work (Sculpt Mode) - but that magically resolved...
Then the Assert also already has its own ticket, see T84530: Failing assert when choosing custom icon for brush

The "messy" drawing is actually the icon drawing without alpha, not sure this is the way it is supposed to be in 2.80 onwards, but that would deserve its own report.

@Bastien Montagne (mont29): you have been on these similar cases, interested?
