I believe this to be a bug with Avogadro
Environment Information
Avogadro version:1.2.0
Operating system and version: Windows 10 Home 1803
Expected Behavior
Simple moving around the molecule to display differently.
Actual Behavior
When the molecule is rotated / dragged / zoomed in and out, the previous position remains in view. This leads to ghosting as the molecule moves across the screen
Steps to Reproduce
Opening or building a molecule then attempting to manipulate it in navigation mode
I am admittedly a new user, so perhaps there is something in the settings I need to change. A characteristic image looks like this: https://imgur.com/a/vc2e24e
Any help is appreciated !
