System description:

OS: Windows 10  (10.0.19045) 64bit

CPU: AMD Ryzen 5 2600X Six-Core Processor  (12)

RAM: 16334

GPU: NVIDIA GeForce GTX 1070 (8081MB)

SM: 50 (Direct3D 11.0 [level 11.1])

Description:

Expected Behaviour:

That the entire manoeuvre node GUI is displayed at any angle of view when close to a planet.

Observed Behaviour:

That the Radial Out arrow disappears at some view angles (seemingly when it is close to overlapping the center circle of the node GUI), when close to Kerbin.

Steps to replicate:

1. Put a vehicle into orbit of Kerbin (365km was used in my example images)
2. Go into the Map view.
3. Create a manoeuvre node on your vehicle’s trajectory.
4. Click on the node so that the 6 arrows adjustment GUI is displayed.
5. Rotate the camera, so that the angle of view to the node is approximately the same as that in the angle in the image below.

        6. While holding the right mouse button move the mouse up and left, so that the angle is similar to that in the image below.

 

Notice that the blue Radial Out arrow has disappeared.

Other Notes:

The issue only seems to occur when the node is close to a planet. I burned so that the vehicle was on an escape trajectory of Kerbin and placed a node on its trajectory, at about 2000km, which was not affected by this issue.
