When placemark(stop Event:false) is used with perspective map, placemark is rendered at top-left of canvas not true location.

Some class was a missing in the css... NB: perspective map is experimental and using overlay may be a little tricky on such a map...

berkayoruc commented 3 years ago

So, what is your advice?

Viglino commented 3 years ago

Test and try... its not working on all browsers and I don't know if the Overlay will move correctly on all devices...
