In my VR headset the `MirrorTexture` and `GlowLayer` blurs appear half as wide as on a single 2D screen. This is ok for the `MirrorTexture` class because it has separate `blurKernelX` and `blurKernelY` properties for correcting the blur width when entering VR, but the `GlowLayer` class does not have separate properties for the blur X and Y. Is there another way to set the `GlowLayer` blur X and Y to different values?

`GlowLayer` on 2D screen is normal width…

`GlowLayer` in VR is half the normal width…

In this case I would recommend to set the mainTextureFixedSize in the option providing a blur size independant from the screen. would that work for you ?
