Still broken in V1.2.7.0 from 10th Dev 2024.
I thought this fix item might be for it but I just tested it and still getting glitches in Leaflet implementation.
• Changed the CoherentGT frame distribution system and views refresh rate to better match MSFS (2020) behavior

Openlayers is fine. Glad I switched to Openlayers, it’s rocksolid. Please don’t break that, I just launched my add on with OL @ Location Manager 2 for MSFS 2024/2020 - Sonicviz and getting positive feedback on the quality.
But it’s nice to have options, and leaflet is a well used library for many reasons, so supporting it makes sense too.
