Hi,

Today I tried making a hillshade from the raster data you helped me out today 
-- after filling empty pixels, everything looks great.

Now, when trying to set the layer symbology to hillshade, I got artifacts with 
the default setting and the recommend bilinear with medium. Looking for a 
solution, I found this conservation about the same issue (I think) from about 3 
years ago; it seems to be a problem still today (working with QGIS 3.12).

       https://github.com/qgis/QGIS/issues/23859

So I tried the hillshade tool from GDAL in the Processing toolbox with 
identical setting, and everything looks great.

I think that the flawed hillshade in the easily accessible Symbology dialogue 
needs some work or a hint to the GDAL tool in the Processing toolbox. It is 
frustrating for someone who is new.

I add screenshots from the bad results in the Properties > Symbology dialogue 
and the raster image from which I started.

Anyway, it was great to have a solution easily at hand ;-)

Best,
Maria
