Artifacts on feed from drone

Hello! Recently bought mini2 and litchi. However, when i connect litchi to drone, i notice significant increase in artifacts from camera. They look like encoding artifacts. It happens even when drone is not flying and standing on ground within meter from me, so doesn’t look like signal issues.
This does not happen with dji fly. Any ideas what to check and how to fix that?

Force Close any DJI app before running Litchi.

it’s closed. Litchi won’t even work with DJI app enabled, or other way around.
