When I use rendercam on an object that has a HUGE scale (1000000 in my case) there is a flickering line of pixels only on the left hand side of the screen. Its size increases based on the scale.
Here is a minimal project PixelStutter.zip (196.8 KB) demoing this strangeness. I’ve been playing around with the Rendercam settings, but I haven’t been able to fix it.
Curiously the issue happens even if the built-in renderer is used, but the Rendercam camera is inside the collection.
It’s very likely a floating point precision issue. Don’t use a crazy scale like that 
It’s actually really cool (and useful) to have borderline insane scales like this in a prototype I’m working on!
It works if I don’t use Rendercam, but I also want some 3D models in there, so I’d like to use it because it’s awesome. Yes, I know. Want, want, want. Did I mention it’s a prototype? Anything goes in a prototype!
I “fixed” this by dividing the sprite being scaled the most into four parts. Viva la HUGE SCALES!
