A clear and concise description of what the bug is.

Hello, thanks for gzdoom

When playing in stereo VR mode I have to turn off the cursor because it is drawn at the same z-depth as the HUD, which means it's at a different location in each eye, neither of which is the actual place where my bullets will go (they go to a spot inbetween).

It's surprising how disconcerting this is, and how strange it is to have to play without a crosshair.

I searched and found this comment from 5 years ago. This PR / issue did not go forward because it would have interfered with the at-the-time immature vulkan work. Hopefully by now that has matured and we can get the crosshair fixed in stereo mode?

Even better would be stereo in vulkan mode, but one thing at a time ;)

Steps to reproduce the behaviour.

Explain how to reproduce

1. use a 3d-capable display like my 3d projector
2. enable a stereo 3d display mode
3. observe crosshair weirdness
4. tweak stereo mode settings
5. fail to make it any better
6. turn off crosshair
7. get killed a lot :'{
