This must be something extremely basic, but I can't figure it out.
I have a selection which I am trying to delete. The layer has an alpha channel, but I want it to stay true to the selection (that is, EVERYTHING in the selection is deleted, and EVERYTHING outside the selection is maintained). When I select it and delete, this happens:

goes to this


It looks like some kind of antialiasing or texture filter, how do I disable it? As in, the selection needs to be 100% cleared to alpha, and the pixels outside the selection need to be untouched.

Sorry but I can't reproduce your result.
I tried it with Free Select Tool and with the Fuzzy Select Tool - Threshold 15, and in both there was no semi-transparency of the selected area.

Ah, I'm quite new to GIMP, I had not realised that the select tool had an anti aliasing option of it's own, and disabling it resolved this issue.
