I have used the processing tools to create XYZ raster tiles from my maps
quite a lot and going through the rest of what is in there I see a tool
to create vector tiles as well. Guessing this might use the GDAL MVT

Yes it does look like the support for extensions in some of the Linux
libraries is a bit illiterate. It would seem like since extensions are
not actually required in Linux that the library creators have not fully
understood how to handle them. Certainly notice issues with Gimp.

I use QLR files quite often and have never had any problems creating
