[4.24] Post-Process Materials Visible only on Right Eye (Left Eye Black)

Seems that in 4.24, Post-Process materials that are set to render After Tonemapping only render correctly on the right eye of a desktop headset (tested Rift, Rift-S and Vive Pro). The left eye is completely black whenever the blendable material is enabled.

  • This happens only in a packaged game, not in VR PIE.
  • No difference between DX11 and DX12
  • Instanced Stereo makes no difference

Using vanilla 4.24.1. No issue on 4.23.1.
Can anyone confirm, and/or know of a workaround?
