Anyone? :) So if I had to guess: Prerendering raster outside the viewport is disabled because for any remote raster source (most are remote) it would overall require QGIS to download much more raster data than otherwise. For users with low bandwidth prerendering/predownloading raster outside the viewport would end up feeling even more sluggish than what I am experiencing. Could that be the reason?
