Hi there!
When I create a blank VR template in version 5.7 and launch the VR preview (PCVR) for the first time, everything works fine. When I launch it again, the screen starts shaking. I’m using OpenXR + VirtualDesktop + SteamVR for Quest 3 and RTX5090. Does anyone know how to fix this?
Could this be related to updates to the OpenXR Application SpaceWarp in the new version? (There were no issues in 5.6.)

Application SpaceWarp is designed for mobile applications running directly on the headset. It shouldn’t be running on PCVR, since none of the runtimes support the extension.
This issue reminds me a lot of the frame desync issues some older versions of UE5 had with OpenXR, although those should already have been fixed.
Khronos added a validation layer into the newest OpenXR SDK, that’s supposed to be able to check applications for just those kinds of issues. It might be worth building it trying it out if you can’t find any other solution. https://www.khronos.org/blog/new-openxr-validation-layer-helps-developers-build-robustly-portable-xr-applications
