COSMIC is looking brilliant, and I'm switching over on WFH machine, but living without Flameshot is unthinkable! :wink: :+1:

Setting the variable XDG_CURRENT_DESKTOP will also not help:

$ XDG_CURRENT_DESKTOP=COSMIC  flameshot
QSocketNotifier: Can only be used with threads started with QThread
flameshot: error: Unable to detect desktop environment (GNOME? KDE? Sway? ...)
flameshot: error: Hint: try setting the XDG_CURRENT_DESKTOP environment variable.

+1 to fix this on cosmic

Flameshot works fine on COSMIC for me. The only thing that's borked for me is #2848, which seems to be independent of COSMIC.

Maybe trying newer versions of COSMIC could help? Idk, I'm new to COSMIC too.

I've got the same version of Flameshot and Qt as you and I've updated to the lastest cosmic by removing the version from the Arch repos and installing cosmic-session-git from the AUR. Unfortunately for me it's not working.

Clicking Take Screenshot in the Flameshot system tray applet's menu...

NGL, if the error is this flakey, it seems like a bug in COSMIC than in Flameshot? But I don't know the internals of either software. Would be better if a maintainer commented here.
