I thinkg, your devices are out of graphical card memory...
Look at the attached picture. There are described how many tiles application needs for zoom 15nm in dependent of MOBAC zoom levels. Default is 9 (16tiles). When you use 12 - appplication needs to display 676 tiles. Each tile is 256x256 pixels.

Next version will have restriction for customizing MOBAC zoom to avoid crashes...

Thanks for your observation.
