[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…

The issue immediately disappears for me (and desktop view starts working again, as well) when closing all Electron-based application windows. They can still be running, e.g. chat programs residing in the system tray are fine, but if an Electron window is open, the segfaults and traps happen, and desktop view breaks.
