Compositor:

• Fixed timing issue for 40-series Nvidia cards.
  

OpenXR:

• Fixed a memory leak when using OpenXR with DX12.
  
• New dedicated OpenXR settings tab and ability to manually enable and disable implicit openxr api layers.
  
• Allow an OpenXR instance to be created even if there's no headset connected and the headless extension isn't enabled. This allows applications and tools to probe the SteamVR runtime for system information.
  
• Provide better logging of errors when multiple application connections are attempted (e.g. multiple OpenXR instances, combination of an OpenVR scene app instance and an OpenXR instance).

• Added a setting to disable gpu bus monitoring. (steamvr.vrsettings section "perfcheck" value "disableGpuBusMonitoring" type bool)
  
• Fixed missing font for many dashboard elements.
  

OpenXR:

• Implemented XR_EXT_active_action_set_priority.
  
• Fixed some issues with automapping Oculus Touch bindings to other controllers when no other bindings were suggested.

SteamVR:

• Fix for crash where GPU would hang due to excessive bus usage.
  
• Mini-perf graph now shows Bus % usage when above 3% (currently Nvidia only). Bus usage measures memory transfer between GPU and system. This typically happens primarily during loading, but can result in catastrophic performance loss when running out of video memory and the OS starts paging critical resources to system memory. The easiest fix in this case is typically to reduce your recommended render target resolution in SteamVR settings, or max texture resolutions in the application’s settings.
  

OpenXR:

• Fixed a bug with visibility mask vertex direction and related two-call idiom behavior.
  
• Fixed an issue for DX12 apps that use multiple swapchains per frame.
  
• Fixed an issue with xrStopHapticFeedback having no effect on HTC Vive controllers.
  
• Updated OpenGL supported depth format. Removed GL_DEPTH_COMPONENT32 and added GL_DEPTH_COMPONENT32F for wider driver compatibility.
  
• Fixed an issue where multi-session applications would get old time information on the first frame of sessions after the first.
