Dynamo Acts Weird

Hi guys,

I have this issue with Dynamo. I’m using Revit 2018 and Dyanmo 1.3.4. When I opened Dynamo, all my nodes are not visible as below.

Things I have tried:

  1. I opened the graph from Revit 2019 and it was good;
  2. I opened other graphs from Revit 2018 and had the same issue;
  3. I tried to uninstall Dynamo 1.3.4 and then re-install it, nothing changed for R18


have you seen this:
Dynamo Locking Up ?

I just did
thanks though.
