There is a problem with fill layers - they receive some kind of line mask after resizing rgb23/HDR document (without any existing mask at all, prior to resize). Look at video.
- create document, add fill layer, switch document to rgb32
- resize canvas to some big value
- look at transparent areas (lines) that occuring over fill layer after resize
