Issue with cut selection

[kmll]

I am a beginner Gimp user and I have an issue cutting from a layer with filter.

1) I have two layers where the top layer has a filter

2) I add an alpha channel to the top layer
3) I make a selection and cut
4) The result is not a hole showing the bottom layer but I get this.

What am I missing?

I can not reproduce that, but it might depend on the image, so if you can attach the Gimp 3 .xcf file.

Things to try, you can add an effect without it becoming an (fx) layer. There is a merge check box in the dialogue.  Otherwise merge the filter from the layers dock.

Fantastic! Checking the "merge filter" option did the trick. Thanks :-)
