Help! Why is OSD flickering on Vortex 150

I bought a second hand Vortex 150 as my first drone. Managed to pair with my DX6i and FatSharks and flew the first battery as LOS as that's what I'm used to with my planes. But when I started carefully with the FatSharks I noticed that the OSD was no longer static, as on the desktop during binding, but flickering around and not readable at all. I tried to hold the drone in my hand: it was ok, but when I shooked it, the text was flickering all over the screen, not possible to read at all.
Any suggestion what can cause this?
