what browser is that for and do you see the same slowdown in other browsers (which I don't see on chrome/Win10)

Hi @adumesny ,

this slowdown happened to me on Googles Chrome and Firefox on MacOS Big Sur latest version, also latest versions of both browsers. In Safari gridstack does not seem to work anyway...
I cannot reproduce these issues on Windows on any browser also...

no longer seeing the issue with Chrome and 3.1.3-dev build (appears fixed), BUT still seeing on Safari! (it animates back to original location (if I force a clone copy I can see old+new), then to new location - hence the 300msec delay before animating to dropped location.

[kevinlandsberg]

@adumesny , correct. Still seeing delays on dropping elements.

fixed in next 3.1.4 release
