Hi Frank and Even I need to investigate further, but I am suspecting that this issue may be specific to the MrSid format. My tests have been with a collection of 24 sid images. I just went back to an older project where I have 188 tiles in GeoTiff format (and similar base resolution) and QGIS works marvellously with this vrt!
