That would point to SuperShot running out of memory, so your graphics card does weird things.
SuperShot requires an awful lot of memory, simply that's how it works. There is an memory estimate in the UI of the plugin, which displays what is needed just for the plugin, on top of what you need for the rest of VaM, the scene, Windows OS in the background, etc. You don't expect this to work on some old Laptop GPU that only has 2GB or something? If you got 8GB dedicated graphics memory, you should be fine unless you have some super demanding scene.
