Black "pixels/dots" after Packaging for Quest 2. How to remove them?

Hey,
i recently made a project in UE4. It’s a pretty simple stereoscopic picture viewer and everything works smoothly for the oculus rift exe build.

However my client now wants a version for their quest so i changed some settings for it to work on android. It seems to work perfectly fine on the Quest 2 except i now have this black dots/pixels, wich seem to be tracked on the VR pawn? It feels like a HUD that shouldn’t be there, and i tried everything in the settings to try to remove them. I am SO confused, why are they here, and why are they tracked on my face??

At first i thought that is has something to do with the Anti-Aliasing settings but i tried out all of the options and at this point I’m close to despair.

I didn’t find anyone that had a similar problem like this and hope that anyone here can help out!

Here is a screenshot of the black pixels/dots:
