Hi,
<div class=""><br class="">
</div>
<div class="">Today I tried making a hillshade from the raster data you helped me out today -- after filling empty pixels, everything looks great. </div>
<div class=""><br class="">
</div>
<div class="">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).</div>

</div>
<div class="">So I tried the hillshade tool from GDAL in the Processing toolbox with identical setting, and everything looks great. </div>

</div>
<div class="">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.</div>
<div class=""><br class="">
</div>
<div class="">I add screenshots from the bad results in the Properties > Symbology dialogue and the raster image from which I started. </div>

</div>
<div class="">Anyway, it was great to have a solution easily at hand ;-)</div>

<div class="">Best,</div>
