 Thanks, @Gunther this may help until the issue is resolved!

There is no issue it think,

 

It is quite logic.

 

Jpeg format does not support an transparant background. PNG does tough.

 

That the background of JPEG is black is quite odd.

[Vectorworks very slow]

Experiencing this now with VW 19 extremely slow when using workgroup library on the server. like it is refreshing every 2 minutes. Why? i dont know. I would like my workgroup refreshed when used but not when using local files
