light2d choppyness, but fps stays the same

3.0.6

was going to post #9944, but i think my issue a bit different.

basically, if you use 5 or more of:

this kind of texture as your light, and scale to 10, and set blend mode to mix, and if those are all rendered on the canvas screen, and when your character moves.. it will create a very noticeable stutter when the canvas moves. i'm on gtx 950

HOWEVER, when this happens your fps remains a steady 144. doesn't make sense i think, could be possible internal bug with light2d?

actually, fps does go down a bit to 137 or whatever, does seem like its causing it. ok well i searched light2d in issue page, so this prob duplicate sory
