I'm experiencing a frequent crash shortly after I exit PIE:
- Fatal error: [File:D:\Build\++UE4\Sync\Engine\Source\Runtime\Windows\D3D11RHI\Private\D3D11Util.cpp] [Line: 345] SwapChain->ResizeBuffers(1,SizeX,SizeY,RenderTargetFormat,DXGI_SWAP_CHAIN_FLAG_ALLOW_MODE_SWITCH) failed at D:\Build\++UE4\Sync\Engine\Source\Runtime\Windows\D3D11RHI\Private\D3D11Viewport.cpp:235 with error DXGI_ERROR_INVALID_CALL, Size=724x124 Format=DXGI_FORMAT_R10G10B10A2_UNORM(0x00000018)
The crash appears to occur most frequently if I'm exiting a non-VR
PIE session, but have a Rift attached. Does not appear to occur if I
unplug the Rift.
Any thoughts on what's going on here & what to do?
Here's the full callstack:
