AppImage launched from `.desktop` file results in crash/blankscreen

I confirm (by marking “x” in the [ ] below: [x]):

• This is not a troubleshooting question. Troubleshooting questions go here: http://www.mattermost.org/troubleshoot/.
• This doesn’t reproduce on web browsers (such as in Chrome). If it does, issue reports go to the Mattermost Server repository.
• I have read contributing guidelines.

Summary

The appimage when integrated with AppImageLauncher generates a .desktop file that contains --no-sandbox (this is default for appimages built by electron-builder: https://github.com/electron-userland/electron-builder/pull/4496 ) If I run the appimage directly or remove that flag from the .desktop, all is well.

Environment

• Operating System: Fedora 34
• Mattermost Desktop App version: 5.0.0rc3
• Mattermost Server version: 5.37.1

Steps to reproduce Download a new appimage, double click to make AppImageLauncher integrate it. Close initial launch (works fine first launch from the AppImageLauncher screen) Relaunch from UI shortcuts from the .desktop file Observe dead app.

Expected behavior no crash/white window

Observed behavior windows open white or crash

Possible fixes find a way to not run this line in builder: args.push("--extraAppArgs=--no-sandbox")

@jsg2021 Just giving you an update, I’m kinda confused why electron-builder has this bit hardcoded in there, since it’s very very difficult to undo it if you want to. I’ve left a comment on that issue in order to see if we can make a change to electron-builder in order to make that optional.

Sounds good. Thanks!
