Bug ID: 56378
           Summary: Microsoft Edge and Edge-based WebView2 do not function
                    without --no-sandbox option
           Product: Wine
           Version: 9.3
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

Microsoft Edge will freeze about 1-3 seconds after launching.

Steps to reproduce:

1. Download and install WebView2 (which includes Edge) from
https://developer.microsoft.com/en-us/microsoft-edge/webview2/
2. Run:

wine "/PATH/TO/PREFIX/drive_c/Program Files
(x86)/Microsoft/EdgeCore/VERSIONNUMBER/msedge.exe" --disable-gpu --no-first-run

Edge will not launch.  If you add --no-sandbox to the launch options, it will
launch, but freeze after a second or so
(https://bugs.winehq.org/show_bug.cgi?id=56377)

--disable-gpu is required wine wined3d, it can be dropped if using DXVK.

--no-first-run disables the first run prompting you to sign in and such, it has
no bearing on this bug itself.

This also affects applications using WebView2, e.g. the Adobe Creative Cloud
setup application:

WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS="--disable-gpu" wine
'/PATH/TO/Creative_Cloud_Set-Up.exe'

Using this at least allows the window to open, though it is blank for reasons
currently unknown:

WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS="--disable-gpu --no-sandbox" wine
'/PATH/TO/Creative_Cloud_Set-Up.exe'
