In script movements picture is twitching

[SHOOTnik]

Hello.
This is my bug.
Stellarium works without any problem. By mouse pan and zoom I have no any lags.
But when i run any script with dynamic movement and zooming i have twitching picture
it seems like shaked flickering. In built-in script "screensaver" it bug appears always.
I tested it on 3 different PCs. On Win XPx32, Win 7x32, Win7x64. Videocards ATI HD 2600,
GeForce gts 250, GeForce gts 450. Processors core 2duo t7100, core i3 2100, core i7 920.
On GeForce's I've installed latest drivers ver 285.58.
But nothing... :((( Bug still the same.
And when i run "screensaver" script cpu usage is 70-80 percent on dual-core processor.
On quad core processor it takes 100% of single core but other 3 cores are unused.
Changing min-max fps in config.ini or script body have no effect.
Maybe can help using parameter "void updateMotion(double deltaTime);", but i don't know
how it works.
I tested 0.11.1, 0.11.0, 0.10.2 versions a this bug always appears
Help me please.

I can't reproduce this issue. Do you can record video from screen with described issues?

[Alexander Wolf (alexwolf)]

I guess, you mean not completely smooth movement of the sky?
