Ghosting, while AppSW activated.

I have a bit of a ghosting problem on the quest 2, while Application Space Warp is activated.
As seen in the picture, i have an simple spline-Mesh comming out of the controller with a plane-mesh positioned at the end.
If i move, i get a strong ghosting effect. It looks like there are two spline meshes several centimeters apart.
Weirdly enough, i tried to capture the effect with screenshots and Video Capture, but couldn't.
In the resulting screenshots and videos, everything looks flawless.
So i tried to capture it with my phone camera. You can clearly see the two beams.
The effect disappears, when i deactivate AppSW.

Does anyone know what this problem might be, and how to solve it?
