VR View freezes when entering world

[JoMaZu787]

When i enter a world the vr view completely freezes, visible in the headset and the steamvr preview, yet the minecraft window on the pc shows my camera perspective moving and rotating with the hmd tracking.

Device: Quest 2 (Connected over wifi using ALVR)
OS: Arch Linux (KDE Plasma)

can you check if toggling VR in the world fixes it?
can do that with right crtl + F7

[JoMaZu787]

can i change that shortcut? sorry am a little new to this mod

[fayer3]

no that is hardcoded, but you can also toggle it in the from mod menu

[JoMaZu787]

nvm i figured out how to disable the kde plasma shortcut that had the same keybind
also yes that fixes it

[fayer3]

hm okay, good that that fixes it, not sure why it get's stuck though
can you post a log from when it gets stuck

It's a known issue that seemingly has to do with SteamVR's OpenGL pipeline. There's nothing we can debug on our end cause it's SteamVR itself freezing the view, while the game window still shows movement. Often the freeze occurs right when the controllers start tracking for some reason.

[fayer3]

could it be related to the fact that we submit two frames for one poll during world load?

[Techjar]

I don't think so cause it can happen while just sitting on the menu.

looks like something doesn't like the eye stencil

[JoMaZu787]

the bug also happens when changing the desktop mirror mode and toggling the lanczos scaler

[fayer3]

can you check if disabling the eye stencil still produces that issue?

[JoMaZu787]

yes it still happens with eye stencil off
