Airplanes on Skyview flickering/blinking on the map

Goodday everybody,

I have a problem since a long time, my Piaware Skyview map shows the planes perfectly, but they are flickering on the map. I use Piaware 3.5.3. My windows 10 computer has this problem in all browsers (Vivaldi, Chrome, Edge).

Even my Raspberry Pi with Raspbian Stretch, radar station that uses Chromium. Can any body help me with a fix? A long time ago in Piaware 2.0 or so the planes where perfectly realtime with no problems, some versions later this problem came.

With regards,

Marcel
