Steps to reproduce:
1. Create new Unity project
2. Import “com.unity.graphtoolkit” package using Package Manager
3. Go to Samples tab and import “TextureMaker Sample” sample
4. Navigate to Assets > Create > Graph Toolkit Samples > Texture Maker Graph
5. Open “New Graph.texmkr” Asset
6. In Blackboard create “Texture 2D” variable
7. In Graph Inspector window > Data Type change type to “Color”
8. Observe the fields, “Show on” text in the Graph Inspector window 

Actual results: Changing “Data Type in Graph Inspector causes “Tooltip”, “Default Value”, “Node and Inspector” fields stretch, “Node and Inspector” dropdown field goes over the “Show on” text
