[QGIS-Developer] Raster reprojection during save

Off the top of my head, what I remember: the way zoomed in resampling
occurs isn't compatible with reprojected rasters. It's visible on the main
canvas as soon as your project's CRS != raster's CRS. I *think* zoomed out
resampling didn't suffer from the same issue.
