Crop drag and resize not smooth

[caroig]

I'm using the vue cropper in a large project with vue 2.x, and vuetify. It all works wonderfully, but the crop window drag and resize has a lot of lag and stutter. The preview window responds immediately when the crop window is dragged or resized, but the crop window lags behind.

Are you handling the drag events ? If so, maybe there's some expensive operation that's causing the lag.
Also check if ui is re-rendering for each drag event.

Yes same its lagging and also sometime browser hang and crashed too.

@caroig I think that part of your lags is caused by a css transition set on your cropper-crop-box.
