I have a small problem using the latest Android Version of QGC on a Siyi MK15 controller. Everything works fine during manual flight. But as soon as I upload a survey waypoint route, the App gets slow after 4-6min of flight time, video stream gets choppy and gets worse over time.
I can fly manually for 30min or longer, witouth any problems in the app.
The system is a pixhawk orange cube with ardupilot 4.07.
I would appreciate any help.
