Bug Description
- Run Stellarium.
- Show Date/time dialog (F5)
- Move cursor to year, month, day, hour, min or sec value
- scroll any of the above with mouse scroller
FPS is always in range 30..60
- Now Call AstroCalc (F10) and Close it (with or without any operation in between)
- try again scroll values in Date/time dialog
- no change with hour, min or sec, but any change in date causes a very big delay (~2..3seconds),
- FPS falls to ~0.3
After processing all the scroller events FPS comes back to usual high value.
Seen in 0.15.2 and 0.90.latest
No problem on 0.14.3.

Perhaps this is related to big list of satellites (16000+), which I play with.
When all the satellites are displayed in wide FOV, the FPS is about 5..10. If I switch view satellites off, the FPS is 30..60 as usual.
Finally I tried to restore the default setting for satellites and after restarting Stellarium the bug has gone. Then I load that big list again, and le voila... I can't switch dates without problems again. Not only mouse scroll causes such a big delay. The same is for keyboard as well.
