Best QR Code Generator for Web Apps?

I had a user report the Barcode class failing on headless Linux servers.

The Xojo Code

var URI as String = toURI( user, service )
try
  #if TargetMacOS or TargetWindows or TargetDesktop then
    Return Barcode.Image( URI, width, height )
  #endif
catch e as RuntimeException
  Return nil
end try

The crash reported through stderr

Jul 26 08:04:40 demo demo42001[828]: Failed to load plugin libBarcode64.so:
Jul 26 08:04:40 demo demo42001[828]: libgtk-3.so.0: cannot open shared object file: No such file or directory

The time I told Xojo Staff about it

Would be interesting to know if this is still happening.
