Comment 33 for bug 1614593

Apologies for double-posting, but in fact, the currently available `gimp` snap has the same issue as the OP. It sometimes works for the very first usage of the cage transform in a session, but thereafter, all warps have weird holes and glitches.

I tried all the PPAs, snaps I could find, but only the Flatpak of GIMP worked for me, so if anyone is running in to this on 20.10 try that.
