Displayed Gumball Bug?

unhandled
#1

This may be one of those I-don’t-THINK-it-looked-like-this-before issues…

Drag-selecting some curves and points, the gumball arrowsheads were black when the mouse was away from the focused View window

…hovering the mouse over the focused View window (Perspective in this case) the colors would come back to the gumball across all the other views.

In this same session, I have a second Rhino document opened – a Rhino 5 model. Switching over to it, the gumball has outright disappeared even though the gumball activation button at the top can be seen as toggled ON.

If I toggle gumball OFF then ON again (for this Thing 5 model), the gumball displayed across all four views has a blackened Z axis arrowhead and stem. X and Y are colored.

Haven’t yet had time to close it all out to replicate it yet.
