Not from just one corner: It is all over. (EDIT: I guess it looks like this in your picture, because the camera is looking in at an angle, from the top left (EDIT2: All the ridges between the fresnel segments catch and disperse the light from the central imagery))
Now, I haven’t been using my Vive the past several months, because I broke it, but the Rift I dusted off to use in its place, whilst waiting for the Pimax, certainly had a lot of glare too, just somewhat different in character, due to the thinner fresnel segmenting, and it never reached as far as any other device, with its abysmal FOV; I actually got this ugly banding effect, where the edges of the video splash you depict faded to black in a few discrete steps, and then it was grey all around (EDIT3: …but that I would ascribe to the black smear fix).
