Description Nicholas LaPointe 2017-08-28 12:22:37 UTC 
1. Open or create an RGB-space image (preferably not blank)
2. "Layer" -> "Convert" -> "Convert Layer Color Space", change to grayscale
3. Undo
The layer now claims to be alpha locked, although it is possible to paint on the layer as if it wasn't.
4. Disable alpha locking on the layer
5. Paint on the layer
Color compositing will be incorrect. In this example, the red channel seems particularly affected (e.g. painting #FFFFFF on an empty area gives #00FFFF, painting #FF0000 on an empty area gives #000000, painting #0000FF on #FFFFFF gives #FF00FF)

Yes, I can confirm the issue.

This seems to have been resolved? I cannot reproduce anymore in 5.0 pre-alpha...

Please reopen if still relevant, perferably with some extra instructions or examples :)
