Importing SamacSys part mangles symbols

I just started using SamacSys’s nifty part search-and-load (aka, and encountered a somewhat nasty bug: when I first place a new part that I’ve imported, the symbols on the schematic get mangled – see before and after pictures below.

I don’t know if this is a problem with the SamacSys importer or a known bug in KiCad. There is a workaround: (1) save the schematic before you import a new part, (2) place the part (and observe mangled symbols), (3) close the schematic without saving, (4) reopen, (5) re-place the part. It appears to work the second time without issue.


I should also mention:

  • KiCad 5.1.10 running on Windows 10 Pro 21H1
  • Only symbols previously loaded from the SamacSys library, e.g. the resistor (R1) and ground symbols are not affected (see below).



Is the samcsys library added to your projects search path?

I assume you mean Eeschema => Preferences => Manage Symbol Libraries => Global Libraries. If so, yes:
