[OpenLayers-Users] map randomly jumps when zooming/panning. enableKinetic issue?

[Dominik Mikiewicz]

Hi,

I've seen this behavior too but never had a clue what may be causing it. The console remains silent.
My observation is that it may happen if there is some more stuff going around - like retrieving data, preparing features and adding them to a  vector layer. In general - the more data is used, the higher possibility something like this may occur.

Hi Eric,
I will post a link when I have a stable version online that shows the issue. I wont have the time to break it down to a minimal example, though.
Had it once with firebug active. it showed no errors.
As said, its not obtrusive and happens very rarely...
