(Which version of Dynamo are you using? Go to Help > About if you're not sure.)
dynamo 1.0.0

Revit version

Revit 2016 R2
(Which version of Revit are you using?)

Operating system

WINDOWS 10
(e.g. Windows 7, Windows 8.1, etc)

What did you do?

Hi, I have installed Dynamo 1.0 but when I launch that from Revit 2016 R2, Revit quickbar immediately becomes blank and all the icons seems invisible (if I pass over an icon I can see the description of the button, but I can’t see the icon!). If I switch the quickbar down, below the ribbon bar, I can see all the buttons running Dynamo, but I’d like to keep it on the top of the screen.
I have uninstalled Dynamo and everything is correct now: quickbar returns always visible.
I have checked my graphic card settings (NVIDIA high settings), my drivers are all updated.
I'm running Windows 10, Revit 2016 R2, NVIDIA GTX 950M.
Any other people found the same issue and reported that on dynamobim forum, but there is no answer.
Please, can you fix that problem?
Thanks
