Camera Not Clearing - intermittent with performance
Hi, The problem i'm trying to describe is what i'd call "trails" behind a moving object - like what happens when you set a cameras ClearFlags to "Don't Clear"
My camera is however set to Depth only, and has been working find for some time. I have an android AR app and use a video see-thru background, and various graphics on top.
Seemingly randomly, my builds started to act as if the camera was set to Don't Clear - the video background would be covered up with the graphics. But this only happened intermittently, ie it would start doing it for 2 seconds, start for 2, stop for two (but not regularly, between 1,3 seconds before switching)
If I add more objects to my scene, the problem happens more often, and eventually is continuous. I'm adding 3D meshes of level design
I'd have guessed it was performance, but the app is running smoothly at 50+fps?
What could cause intermittent camera clearing issues? (if it is indeed that)
