Blinking layers HERE vector maps

Background:

I'm working on integrating HERE maps with trucks restrictions to our web-based software solution.

Issue:

Halfway through the integration, I've noticed that when zooming-in/zooming-out the labels and truck restriction signs are blinking after reload. I've captured same behaviour in the example provided by HERE (link) themselves.

As the issue occurs in their own examples I think it is safe to state that it's not my implementation problem.

I've seen (also in their examples), that when their vector tiles are integrated using mapbox.gl, the zoom-in/zoom-out becomes smooth, but I would prefer to use their own javascript library due to other advantages (like traffic incidents display, etc.).

Question:

Anyone has any ideas how could that be solved?
