I recently added a Camera2D to my scene, set it as Current, and now the launched app freezes at the Godot spash screen (the window doesn't respond so I have to kill it with the Stop button).
Going through removal of all nodes until the freeze disappears, here is what I got:
- Root (Node)
And I noticed that ParallaxLayer.Mirroring was set to (0,-512).
I reset it to (0,0) and now the scene plays correctly.
It seems I can set positive values but once X or Y is negative, the freeze re-happens.
The GUI allowed me to set -1, but it confuses the engine, so is this a bug?
