While I do understand, that the resolution in VR will be lower than outside VR, it seems that the image is more blurry than it should be. Here are two example screenshots:

If you look at this jagged edge of the diagonal line and compare it with inside VR (see arrow), you can see the difference.
The browser is Chrome 70 on a OnePlus 6T with a screen resolution of 412 x 892px and a dpr of 2.
Is this the expected behavior? Is there something I can do to make the VR image clearer?
