Picture is blank

plugin version: 5.1.0 idea version: 2021.1 graphviz version: 2.44.1

There are contents:

@startuml
alice -> bob ++ : hello
bob -> bob ++ : self call
bob -> bib ++  #005500 : hello
bob -> george ** : create
return done
return rc
bob -> george !! : delete
return success
@enduml

The saved picture is normal.

It was able to display normally before, but the picture was abnormal after I upgraded the plug-in version. I rolled back to version 5.0.0, but the preview image is still blank.

I’ve added some debug info, maybe it will help: Please try it: plantuml4idea.zip (you can drag it into the editor, or use dialog, without extracting)

Hmm the plugin contains 167 jars (103MB). I was looking only to the main one. Anything could be going on there. But are you really sure that it is caused by it?

I think the possibility is 90%. I tried a fresh installation of IDEA, only keeping these two plug-ins, and even changed my computer.
