hotspot flickering video with alpha

[uwemayer]

I am still very happy to use ForgeJS.

Just compiled it on mac os. 10.14.6

Unfortunately I get a flickering looks like a wrong refresh/redraw of the hotspot
when video with alpha webm (VP8/9) is used.

I would be very glad if someone could help. I attach part of code and
the screen video.

Many thanks and best regards
