Do you have those extra pixels popping up like this ??

Could be any color type of pixel or velocity ...like an extra layer in your visual snow , like some of the pixels stand out more for nanoseconds again again. This video is just effect of glitter. Dont take it too seriously. But im trying to show it somehow. My VSS is like many layers , but some of the pixels i see them running but stand out more glittery . Especially when i obsess over it i notice it way more fast... Btw High up your brightness to see it .
