GIMP 3.0 RC3 Flatpak: missing GEGL operation 'gegl:paint-select'

I’m trying to enable the paint selection tool in GIMP 3.0 (flatpak).
However, the option is grayed out in playground settings stating the missing GEGL operation ‘gegl:paint-select’.

What am I missing?

Since operations from GEGL Workshop are unstable by nature, they were disabled: Do not build workshop operations for stable releases (including RCs). · flathub/org.gimp.GIMP@c2f07e1

Despite GIMP 3.0 RC3 being distributed on the Beta channel, it behaves like a (almost) stable version so that needed to be disabled.

Thanks for your clear explanation. I was not aware of that. Does this also apply to appimage?
If so, what’s the workaround?
Build Gimp myself?

You may also use the nightly flatpak. I see it has still the workshop enabled and probably ever will (nightly is unstable by nature).

What you can do too, to get the workshop filters on a stable build is to grab the .so file (would be a .dll in Windows and something else on macOS) from an unstable build (official one to be safe) and put in the user directory. See “Find where to put it” section in this article: barefootliam: GEGL Plug-Ins for GIMP. Part One: Using GEGL Plug-Ins

I think the file would be called gegl-workshop.so on Linux (again, change the extension depending on platform).

Then restart GIMP, it would find the op, and the tool would be available.

For 3.0 RC3, no, because I forgot to disable it before the release. But the workshop disabling will apply to the final 3.0 appimage: gitlab-ci: Do not build GEGL workshop for AppImage while we are stable (74a05bc9) · Commits · GNOME / GIMP · GitLab
