Can WebView2 work on Linux+Proton?

[jaredkrinke]

Has anyone investigated running a WebView2-based app on Linux using Proton?

E.g. if you have a browser-based game on Steam that uses WebView2 (instead of Electron--to avoid unnecessary bloat), is it possible to run that game on Linux using Proton?

I suspect the Evergreen installer wouldn't work, but has anyone tried with Fixed Version?

I investigated this a bit and the short answer appears to be: no, it doesn't work (tested on Proton 7 and Experimental).

You immediately get a "BrowserProcessExited" process failure event. I tried various Chrome command line flags (e.g. "--disable-gpu"), but those don't make any noticable difference.

This isn't a surprising result, but I thought I'd at least note it down here.
