Yes, it’s very close to their glare test footage. Not as bad, but still very pronounced. However, some people report only minor glare at the bottom…

Yeah, but the glare most people are referring to here doesn’t have anything to do with the light seal.
I thought the first number was width and the 2nd number depth?
I have been able to reduce or eliminate glare by moving the VP up or down on my face.
There are two primary artifacts with pancake lenses in particular: glare (somewhat focused stray reflections) and haze (generally scattered light). Over 90% of the light from a backlit LCD or an OLED does not make it directly to our eyes. Most of that light gets through the pancake lens but then hits our face where a lot of it is scattered back into the pancake lens.
If ambient light gets in through the seal while in a lit room then some of that that ambient light also makes its way into the pancake lens to decrease contrast, creating a more hazy (ie less black blacks) background. Similarly, in a totally dark room (or with a great seal), as the content gets brighter there is more light scattered from the display itself – also decreasing contrast for more haze.
The glare, or what seems like ghost images or duplicate image detail, is due to the first light coming from the display bouncing just a few times inside the lens and then into our eyes. The more bounces, the more that glare becomes general scatter.
What is interesting is that the glare is actually always there. But at a certain point the haze overpowers the glare so those details are masked. As the content becomes more overall dark the haze will decrease so that the overall black level increases enough that the glare becomes more visible. But if there is any ambient light getting in then glare won’t be as visible. This is why some people don’t see glare artifacts during demos in a lit room or with generally bright content without a whole lot of dark. The contrast just isn’t good enough to see it against the hazy background.
Glare artifacts can also move because where we see them depends on where the bright image content is in the image. You can somewhat adjust the headset to make a particular glare less visible, but typically that just means the glare from other bright content comes into view.
Note that these artifacts are very similar between an OLED display and a backlit LCD. It is the fact that so much light is scattered outside our eye locations that makes the pancake lens the true limit of image contrast rather than the native contrast of the display itself.
Note that “haze” in this context is not meant to suggest the artifact is extreme, just that you’ll never see complete blacks with the display technologies currently being used with a pancake lens whenever there is visible content.

I have some glare. Produces a kind of haze along the bottom. It's internal, not light leakage. I have a different size light seal coming to see if the change in position relative to my eyes help. It's not a dealbreaker, but a little bit of a downer.
