[BUG] Error 303 & vrwebhelper crashes

[dsalt]

I'm reliably seeing error 303 along with some vrwebhelper crashes, all in libcef.

First time properly poking at SteamVR in quite some time. I had error 108 initially, then I moved steamvr.vrsettings out of the way, which due to the permissions problem initially led to “plug in your headset”. I determined that this was a USB device permissions problem related to eudev. I know that the display's working and that the audio device is detected.

I don't remember when it was last all working, but it may have been before fully upgrading to daedalus.

Still happening.

I'd test with --no-cef-sandbox if I could…
