VRAM Creeping up on enabling/disabling VR

[btaft]

I noticed that when switching between VR and 2D repeatedly that the VRAM used would steadily creep up until the point of running out and crashing. I first noticed this when learning to use the Leonardo Maddog and having to switch to a 2D view in order use a couple of the windows because they were not clickable through the glass. But I also tested it with the default Maule and each time VR was cycled enabled and disabled it would creep up while sitting still.

example

VR disabled - 4.1 GPU
VR enabled - 5.2 GPU
VR disabled - 4.5 GPU
VR enabled - 5.6 GPU
VR disabled - 4.9 GPU
VR enabled - 6.0 GPU

and so on

Tried it and confirm.....with every switch cycle the Vram rose till running out of vram and exiting.

Same here.
Every switch cycle enable/disable VR causes a creep up of Vram until crash.
Gone back to v4.5 for now. Works great.
