Unreal Engine Tonemapping Right Eye Flickers

Hello there! 

I compiled the 5.2 oculus branch and have been working on my project using the vulkan subpasses enabled. Everything seems to work great except I have noticed the very very right corner of the display seems to hang/flicker? It's only noticeable in the right eye on the very edge. It's very apparent on the quest pro. On the Quest 3, it almost appears as black dead space. Has anyone encountered this issue?
