[2.117.1] [Visual] Black box from Glyph Trail flare during Overclock

InvestigateXM

When you draw a glyph, a flare will appear each time you hit a glyph point. If the long arm of the flare is randomly rotated into the camera feed in the background of Overclock, a black box will appear and fade out together with the flare. I assume its the sprite of the flare which isn't transparent for reasons unknown.
