Main window randomly unavailable when running on Wayland

[travier]

First, this works as expected with XWayland in a KDE Plasma Wayland session on Fedora 35.

But if I try to run it Wayland only via:

GDK_BACKEND=wayland flatpak run --socket=wayland com.slack.Slack --enable-features=UseOzonePlatform --ozone-platform=wayland

I get no main window but Slack itself appears to be working and connecting as I can see the status changing in the application title in the KDE panel. If I try again several times, I randomly get a working main window that as no major issue as far as I could see.

So this looks like a race condition somewhere thus I'm filling this one here to get suggestions.

Thanks for the good work maintaining this Flatpak!

Same here, except I can only get it to load on xwayland with --disable-gpu (see #154). Using nvidia drivers, btw.

Even this does not work for me.
