Question about how `queueIndex` in `XrGraphicsBindingVulkanKHR` is interpreted.

3

I assume after the XR runtime gets the queue index, it would want to get the `VkQueue` by calling `vkGetDeviceQueue`? But according to the spec, for `vkGetDeviceQueue`: > VUID-vkGetDeviceQueue-flags-01841 >...

Picking an initial OpenXR version

Inconsistent word breaks in enum XrSceneMarkerQRCodeSymbolTypeMSFT

3

The enum entry `XR_SCENE_MARKER_QRCODE_SYMBOL_TYPE_MAX_ENUM_MSFT` separates "QRCODE" differently to the other entries in this enum. `QRCODE` vs `QR_CODE` Better would be to use the symbol `XR_SCENE_MARKER_QR_CODE_SYMBOL_TYPE_MAX_ENUM_MSFT`, with an additional `_` from...

3

According to the docs, the `XR_HAND_TRACKING_AIM_VALID_BIT_FB` in `XrHandTrackingAimFlagsFB` indicates that "Aiming data is valid". But it's ambiguous what valid means in this case: my initial assumption was that invalid data...

xlib and xcb graphics bindings contain several unused fields by every compatible openxr runtime (Monado and SteamVR)

1

`XrGraphicsBindingOpenGLXlibKHR` and `XrGraphicsBindingOpenGLXcbKHR` contain the visualid and fbconfig fields, but they are unused in Monado and SteamVR, the only runtimes that are able to use these graphics bindings. This will...

No way to transition out of SYNCHRONIZED state from the application side

3

The only state available from SYNCHRONIZED/FOCUS/VISIBLE is STOPPING, and that can only be initiated by the runtime. Calling `xrEndSession` from SYNCHRONIZED generates a `XR_ERROR_SESSION_NOT_STOPPING`. This might make sense for normal...

clarify `xrEndFrame` behavior for overlay sessions.

1

This line: https://github.com/KhronosGroup/OpenXR-Docs/blob/2b616d9f33cd4b48a0b0d9db5529886b58b08f49/specification/sources/chapters/extensions/extx/extx_overlay.adoc?plain=1#L194-L196 is slightly ambiguous. What exactly does "ignore" mean here? Should the runtime retain the most recent image, or should the runtime not show the overlay session for...
