I have Glyphs Version 2.4.1 (983) and experience two issues:
there is an issue with ‘set crop to layer bounds’ if a placed image is rotated.
the second issue is that after something is drawn on a glyph with a background image then the ‘component from selection’ option is unavailable when right-clicking.
Thank you
One more addition: It would be helpful if there was an option to be able to release the cropped image from the layer bounds to see the original image.
