Thanks all. My System setup:
1 - VPX 10.8 released version 2051. The EXE I run is VPinballX_GL64.exe
2 - Quest 3 through Virtual Desktop
3 - All VR table I tried having the same issue
3 - SteamVR
4 - CPU i7-10700K, GPU - RTX 4080 16G
Tried press numlock 5 to center. but no luck. Seems the image is not full screen. Only 1/4 (bottom left) of the screen has the image
OK
1 - Fine
2 - I suppose your VR desktop with PC. (I never understood what means "virtual desktop". For me "virtual desktop" is a software only run in Oculus quest. No PC).
I suppose that VR desktop is centered and when start the table, The popup table VR window is centered.
3 - Fine
4 - I had error message when try to run with SteamVR. So I run with OpenComposite.
Nowadays, I am playing with Last VPX GL 10.80 - 2051 from VPX laucher.
You can see from this VPX launcher folder the file "openvr_api64_steam.dll".
So try to change to OpenComposite render mode if you are start VPX GL 10.80 - 2051 direct from "VPinballX_GL64.exe"
There is a developer file where are missing some dlls. Also, in GITHUB there a recommendatiion about SteamVR dll downloads


5 - Fine
