- When I enable the "Observability" plug-in, the exploration of the sky is slowed.
- When I turn off Stellarium, the system report me an error of Stellarium.
Another bug: When I click the "location Window", also the atmosphere and fog is enabled.

Please give info about your system: operating system, GPU and drivers.

1. Please give info about FPS before enable the "Observability" plug-in and after enable.
2. Which error? Please write error message.

3. If you choose planet with atmosphere in Location window, then enabled atmosphere effects is correct.

I, too, see a significant slowdown in FPS (50% or more) with Observability Analysis turned on. But I never thought it to be a problem though - just the added calculations and overlay of the text. I've not had any crashes associated with this plugin yet.

I have noted that if you turn off the Atmosphere and then click on the Location /compass icon the Atmosphere will turn back on. Also if you change locations, the atmosphere turns back on. I don't know if this a bug or "just the way it is"..

My observation about when the Observability plugin slows down.

If I turn on the Observability plugin I see a 60% drop in performance. 45FPS down to 18FPS. This is with no object selected.
But if I select an object and then turn on the Observability plugin I see perhaps a 1-2% drop in performance.
Just toggle back and forth between an object and the background sky to see this..

Why it happens I of course do not know. To me this is a low-importance bug or another "just-how-it-is" sort of thing.

[Expired for Stellarium because there has been no activity for 60 days.]

As a general rule, separate issues should be tracked in separate bug reports.

So, which one of the two issues is classified as "Confirmed, Medium"?

[Alexander Wolf (alexwolf)]

two users have slow down of the plugin - point 1

[gzotti (georg-zotti)]

Report from 2012. Still relevant? One of the PCs mentions antique graphics hardware. I think if Janitor expired something of this kind, it should be left buried. There are enough real issues to go after.
