VR Single Pass white flashing right lens

[Terry1718]

When using VR in single pass mode, in my right peripheral vision there is a very distracting white flashing effect on ground / water textures. It doesn't exist in stereo mode but the FPS takes a big hit. I'm using a Pimax 5K but on other forums I've read that it also effects Vive and Odyssey but it is more noticeable on the Pimax because of the wider FOV. Are the developers aware of this and is a fix likely? I'm using P3DV4.5. Thanks.
