Hi! OP here - the discretization effect is also known as the "screen door" effect. That can be even worse when the VR is trying to provide a picture of a picture.

It's improved a little bit, but still takes a lot of tweaking to maximize readability. I'd say it's "maybe passable" for most users without a lot of patience to do that tuning and compromise in favor of density over beauty.

So it might not be there for you yet - but it's moving in the right direction.
