Tested versions

This was introduced by #114175, in the commit prior compatibility motion vectors work correctly.

System information

Tested on Meta Quest 3 - Master Branch - Compatibility Renderer

Issue description

Initially, motion vectors are broken due to an incorrect reference to .data here which makes the shader fail to compile. This should just be prev_scene_data.

Upon fixing that though, all geometry in the spacewarp sample is rendered as black, while occasionally flashing its correct colors. Unable to capture it with a screenshot, it looks normal when attempting to take one.

Steps to reproduce

Run the spacewarp sample with the compatibility renderer.
