Edge blending (right and bottom edges) not works while the grid deformation is enabled in fullscreen

[pyrochlore]

I found when I try to use edge blending with grid deformation enabled, the blending works only in window mode. If I toggle the app to fullscreen, the blending of right and bottom edges just gone. Any idea about this?
p.s. I use window version

Hey pyrochlore

deformation change the quad perspective and the fullscreen mode change the canvas perspective.
First you need to go to fullscreen mode then toggle deformation on. select deoformation mode, set the grid if needed and then you can start crop on your right perspective.
good luck .
