Sallyanne and rich2005, you are right about this occurrence being present in G'MIC; at least in the Samj-Details-Sharpen [Wavelet] filter.
An interesting test is that after applying alpha to lock to the layer and then using a brush to scribble on the layer in the transparent area, none of these scribbles will be visible. But after G'MIC Samj-Details-Sharpen [Wavelet], in the preview these scribbles are clearly visible.
rich2005, alpha to lock was a smart solution!
However, when using the filter via Filters-Enhance-Wavelet-decompose and having applied alpha to lock, the result presents a black halo (or with part of the background removed when this is the case) around the image.
In the case of G'MIC, care must be taken when selecting the output. If the option chosen is 'On site (default), ok. But if "New layers" is chosen, the result will display a black background (or the entire image will be displayed if the background is not transparent).
Grateful for the attention!
