Dear Maintainer,
Cage transform creates visual glitches. These glitches appear just after
selecting the cage transform area, before any transformation are applied at
all. Sometimes these glitches appear in a totally different part of the image
than where the cage selection is at.
To reproduce:
- Create a new 256x256 image
- Put a bell pepper stamp in the upper left corner
- Make a four point selection using the cage transform tool on the bell
pepper in the upper left corner
- Now a large visual glitch (a heavily geometrically distorted bell pepper
but no distorted colours) may appear in the lower right corner
- After pressing Enter to apply the cage transform, the visual glitch will
stay in the image, even if to points of the cage transform selection were moved
anywhere
