Resolved Blackboard (properties) and preview panel is blank!

Hey, I'm experiencing some difficulties and I can't find any solutions!

I'm using Unity2019.1.5f1 with Shadergraph v5.7.2.
I don't know what causes this, but just out of a sudden the Blackboard (property) and Preview panel doesn't render anything. I can't edit properties.





The same Shadergraph asset doesn't have this error when being imported to a newly created project.
So I tried to re-import assets, deleting library folder and other temporary folders, removing and re-installing Shadergraph, upgrading Shadergraph to latest one, but couldn't fix the issue.

++ This already happened more than three times!
This is frustrating since I had to create a new project and reset all eligible settings again! And that doesn't guarantee it won't happen again in future!

Does anyone experiencing this issue as well?

 

OK, now I finally found some workaround to solve this issue.
I use 2 monitors on my desk, and I use the Shadergraph window on the second monitor(detached from editor).
I tried to dock the panel back into the editor, and this refreshes the Shadergraph window.

 

I spent hours searching for an answer to this. Happened to me as well, so it might be a bug. Absolutely nothing could fix it and it happens consistently. Did you submit some sort of a bug report for this? If not, I'll go do that. It's really frustrating.

 

Yes, I've submitted a report!

 

Unity QA replied that they need more information regarding this issue.
If anyone is experiencing the issue, please post a reply below!

Unity QA was partially able to reproduce the issue on Windows.
This could happen if the Graphics API is set to OpenGL.

 

Same here, I'm using 2019.1.10f1, shadergraph 5.16.1, working on mac and using only Metal Graphic API.
a bit frustrated and finally solved! thank you @NGC6543
