Developer Notes

The other issue, where duplicating a node causes the copied numerical value to be removed from the clipboard, is unfortunately a won't fix, as nodes are duplicated by copying their ToString value to the clipboard and immediately pasting it back into the graph. This behavior is consistent with other instances of duplicate in the editor (such as duplicating an object in the Level Editor).


When copying the 'Value' of a color from the color picker within the material editor, and pasting it into the value field of a new color picker dialog window, it stretches across the screen and causes visual issues.

Upon further investigation, it seems that the pasted information contains code for the Color Picker dialog window, instead of just the numerical value that should be getting copied.

Steps to Reproduce

1. In any new or existing project create a new material and add a Vector3 node.
2. Set the 'V' or value slider to any random number.
3. Copy that value to the clipboard (Control+C)
4. Create a new Vector3 node and paste (Control+V) into the value field.

Outcome The Color picker stretches across both monitors and disables windows aero theme.

Expected The value is pasted correctly into the field.
