Any way to blur without it filling the all canvas of un-transparant color?

I’ve been avoiding the FX > Blur thing for a while because I can’t seem to use it without filling my canva of an un-transparant color.

I’ve done the whole process to explain myself:

When I get to the blur option, it always does this:

Did I forget to uncheck something so that the canva don’t get filled? Maybe the ink?
I tried to find documentation or someone who had this issue but I couldn’t find anything about it :sob:

you are most likely using indexed color mode.
