Disappearing POI

While making a jump in Spined Lizard Lagoon, or in the hoodoo hills the POI is disappearing and appearing. Also, some of the rocks are not solidified at sll.

While making a jump on Panjura official server map, the questing poi that you're currently in named Spined Lizard Lagoon is disappearing starting the quest failure, and going back to normal as you touch the ground or after a few seconds.
Edit 1. Problem appearing in other pois as well for example Hoodoo Hills

poi's still visible while making the jumps.
