I have downloaded several SRTM DEM raster tiles from https://dwtkns.com/srtm30m/, and created hillshade versions from the tiles. However, upon closer inspection, the hillshade tiles now have border lines that I do not know how to hide or remove (like in the image below, which shows the border lines of the 4 tiles):
I tried checking the Styles options but cannot find a way to hide the lines/borders. When trying to render the tiles as singleband pseudocolor, no lines are shown, so I am suspecting the lines are only generated when doing a hillshade render:
How can I hide/remove these hillshade tile border lines?
