We are issue with js API 3.11, when we hide the mapdiv and resize the window and when we see the map again it doesnt work properl and goes out of extent.Also we can see some error in developer tool. - Error: Invalid value for <circle> attribute cx="NaN"
We have tried handling map resize manually as suggested at this link Hidden map becomes currupt after browser resize but still the map is not working properly.
We've put a quick example of this behaviour here: http://jsfiddle.net/ZM3SM/164/
Thanks & Regards,
