Regarding login issues a quick workaround is to close the original slack instance before you click on "Open" from your browser.

For me screen sharing works. And the first time I can share the whole screen. Not only some windows. I have the following installed.

slack-electron 4.34.121-1
electron 1:25-1
electron21 21.4.4-1
electron24 24.8.7-1
electron25 25.9.0-2
egl-wayland 2:1.1.12-1
wayland 1.22.0-1
wayland-protocols 1.32-1
xorg-xwayland 23.2.1-1

Screen-sharing is broken for me as well.

FYI - Screen-sharing is broken on Wayland using Electron25 and Slack 4.34.121

@roukoswarf Right, then the segfault isn't universal, I'll update the package.

No segfault here on 4.34.120 as pulled today with --ozone-platform=wayland on kwin on electron 25.

sha256sum fe2c78539f31cf8e58ae2250af428d00637f0d59af987113f31d7f0f8db48d72

exec electron25 --ozone-platform=wayland /usr/lib/slack/app.asar "$@"

Did some more debugging, here's what I get from gdb for the segfault (4.34.120 + wayland):

$ gdb --args /usr/lib/electron25/electron \
  --ozone-platform=wayland \

This doesn't say much to me, but maybe to someone else.

Perhaps 4.34.120 is better on wayland than 4.34.115?

The latest version, 4.34.115, crashes on launch for me on Wayland, both with Electron 24 and 25.

Holding the package at 4.33.90 until I have time to investigate. Feel free to build and test the latest version yourselves, help is very much appreciated.

@amezin Regarding the Electron version, with v25 + Wayland Slack segfaults on launch for me, hence the dependency to v24.
