Jerky animation

[NotSoRandomOne]

#601 # Actual Behaviour
If I lock onto a planet, like Mars, then hit 'J' or 'L' a few times, to speed up or reverse the time flow, the animation is real jumpy, about one jump every second or so. I've never seen it in Stellarium before. I had made the ground invisible, and eliminated the fog and atmosphere, if that has anything to do with it, but toggling those doesn't seem to affect the problem. Only right-clicking on the background, to un-lock the currently locked object, makes the animation go smoothly again.

Steps to reproduce

Open Stellarium, left click on the moon or a planet, then speed up the timeflow with 'J' a few times.

System

• Stellarium version: 0.20.0
• Operating system: Win10
• Graphics Card: NVidia 960M

Yes, it's a side effect of listing "hourly motion". Go into settings/Info and click away "Proper Motion". Currently I don't see a better solution.
