[OXR] ovr_CreateTextureSwapChainGL_Impl failed: Unsupported depth/stencil texture format

Hi,

can't get on Oculus Quest 2 depth swapchain with neither of reported supported swapchain formats for opengl in OpenXR API runtime always reports  Unsupported depth/stencil texture format OVR_FORMAT_R32_FLOAT. I have tried to pass GL_DEPTH_COMPONENT16,GL_DEPTH24_STENCIL8,GL_DEPTH_COMPONENT32F, GL_DEPTH32F_STENCIL8. However for all passed depth formats error is the same. 

 

some info of the env:

------

Using Native api with depth works (OVR_FORMAT_D24_UNORM_S8_UINT) 

any workaround , seems like a a bug in OpenXR implementation ?

  • e32a I believe I was able to replicate an issue like this and the fix was shipped in the latest public test channel builds. Would you mind testing again to make sure that it has been fixed for your GPU?

    the problem seems to be in using XR_SWAPCHAIN_USAGE_DEPTH_STENCIL_ATTACHMENT_BIT in the xrCreateSwapchain , if removed, then depth texture can be created.  Would be great to get some more explanation on this 'feature'. Is this flag valid only  for Dx graphics ?

  • e32a Thanks for the report. Trying to narrow this one down a little - are you using an NVidia or AMD GPU to reproduce this issue?
