I think i‘ve posted a workaround somewhere else on this forum. It’s basically just disable and enable DLSS after switching to XR.
have not looked into SSR without raytracing, my fix is only for raytracing.
Edit: saw in the issue that’s related to raytracing, but not to XR. I’ve noticed the wobbling, too. But going to earlier version is also not an option, as performance is worse in earlier versions of Unity.
