Select By Color tool

[meghan_e]

I've been working with Gimp 2.10 for a long time. I'm not a Gimp expert at all just like playing around.
Anyway, I installed Gimp 3-R2 and was trying to do a simple
transparency layer -> Filters -> Render -> Noise -> Solid Noise.
Then I went to the Select By Color tool and it won't select anything.

I tried these exact steps in Gimp 2.10 to be sure and it works fine.

Is there something else that needs to be set up? If there are instructions, I'm happy to read them, I just haven't been able to find anything about it.

Thank you!!

Yes, I got caught out with this.  A GEGL filter, is applied as a layer-effect - that little fx icon showing.

You can merge that filter, but easier when you apply the filter, have that "merge filter" option ticked.

   

Edit: Just in case it is missed, a right click on that fx icon brings up various options.

Just FYI, this *should* be fixed for the final 3.0 release with https://gitlab.gnome.org/GNOME/gimp/-/me...uests/2122 .
