i have a problem on Oculus 2 (UE4.26.2, armv7, vulkan) with stereo layers. I am using that trick with live texture setting from UI widget render target and when i am switching levels it starts to flicker after a few switches. It looks like some buffer is not cleaned properly.
Is there any low level API to properly clean that or to destroy these layers on level switch ? When i use multiple stereo layers it starts to flicker after the first level change.
