Blinking on resizing

Hi,

We use the following code to redraw on resize:
const rect = diagram.getContentBounds().clone();
diagram.zoomToRect(rect);
diagram.invalidate();

But it leads to diagram blinking during resizing. Is it possible to avoid blinking?

Hi Anna,

Check if it's any better if you replace invalidate() call with repaint(), the latter doing an immediate repaint of the canvas. Also assuming you have diagram.setVirtualScroll(true) set, otherwise there are are lot of DOM operations like resizing and scrolling that might interfere before the repaint.

Regards,
Slavcho
