What happened?

We use the RVOverlay node to make stereo floating windows, using similar property commands to those below. This worked as expected up through RB-2.2.0-VFX2023, but as of RB-3.1.X-VFX2024 renders a diagonal line through the middle of the image.

I've confirmed the issue also exists in the latest OpenRV main branch, 4.0.0 (3f56ee1).

To reproduce:

  1. rv [ solid,red=1,green=1,blue=1,width=1920,height=1080.movieproc solid,red=1,green=1,blue=1,width=1920,height=1080.movieproc
  2. Open a python console, and execute the following commands:
commands.newProperty("sourceGroup000000_overlay.window:DCinema_left.eye", commands.IntType, 1)
commands.setIntProperty("sourceGroup000000_overlay.window:DCinema_left.eye", [0], True)
