So, after fiddling around a bit more, I can see that when zoomed at native
resolution or further out, the "Zoomed out" option works, with "Nearest
Neighbour" showing the source pixels and "Cubic" and "Bilinear" applying
re-sampling.
The options in the "Zoomed in" however do not seem to produce any
Thanks for the replies.
The imagery I'm working with comes from drone mapping.
The orthomosaic is generated using OpenDroneMap, in WGS84 UTM CRS
The resulting GeoTIFF is then re-projected to Web-mercator 3857, before
being run through gdal2tiles.
At this stage I'm loading the tiles as an XYZ laye
There's a lot of questions about the context of use of an XYZ layer that
you haven't given us detail of.
Are you referring to a layer loaded into the Qgis canvas via a data
connection or some other context involving XYZ layers?

That looks like the layer's resampling is not set to nearest neighbor.
Also be aware that QGIS will have to resample the tiles whenever the
scale of the map does not match one of the pre-rendered zoomlevels of
the source (and the same CRS). If you have a matching CRS, select the
layer and clic
( bringing it back to the list :-) )
And are you sure the image retrieved from the xyz server is not a jpeg
(compared to your original png)?
You can try to see the actual url's used via F12 (the Debugging Development
Tools panel) in QGIS.
Another option: QGIS does not respect the xyz-zoomlevel

Hi Stephane,
From what do you conclude that there is anti-aliasing going on with XYZ layers?
I use xyz layers also but I'm not aware of such behaviour

Is there a way to disable anti-aliasing of the png tiles loaded on an XYZ
