Repro:

  1. Create a mirror
  2. Create a downward pointing projector in front of the mirror
  3. Look at the projector in the mirror so that you can see the bottom face of the projector.

Observed: There is a plane of light on the projector.

Original report: Sometimes, lights show up as square planes instead of their real shapes. I’ve made a video that shows the bug https://youtu.be/PA8bI-G2MG8?si=204jd7Xxsb9CSfzu You can see the problem in the upper left corner of the video. It does not affect all the lamps in the room though.

Thank you for looking into this. Kind regards
