Description
So for context, I've been making myself a guide for learning Gimp and Pinta as a Paint.Net user. Throughout all of that I have found several effects that have issues rendering their effects correctly when an used on an alpha channel.
To Reproduce
Just using the effects like normal.
Effect List
Ink Sketch
Fragment
Motion Blur
Radial Blur
Zoom Blur
Version
Rocky 9, Flatpak Pinta
Example
Fragment on a solid background - Working Correctly

Fragment on an Alpha Channel - This glitched outline looks white in pinta, and looks even stranger here.
