same story on fedora 35, gnome 41 and wayland

Ok, since we have two people with the same issue on two different distro, let's do some testing. I would appreciate if both of you file the steps and report back the output here:

1. Open two terminals and keep them open
2. In the first terminal run:

pkill flameshot
flameshot

3. In the second terminal run:

flameshot gui

According to your posts nothing should happen, but you will see some output in the first terminal. Please provide us that output.

Additionally, @pashtet422 please provide the following:

• Your Flameshot version
• how have you installed it (compiling from source, RPM, Flatpak, Snap, ...)

Was about to add a "+1" on this, but executed your procedure above, and it worked. So, it's my understanding that, on order to flameshot gui to work, the daemon should already be running; is that so? Reading the docs, it wasn't clear - and I was under the impression that running flameshot gui would start a one-shot capture, regardless of the daemon.

Using latest stable Snap version, BTW.

[mmahmoudian]

@ivocavalcante all flameshot gui does is to call DBus and ask the daemon to start in gui mode. Therefore if you want to have single command, you are better to call flameshot ; flameshot gui. As far as I understand, it is in the implementation that the flameshot gui starts the daemon if it is not already in the background. This behavior is definitely the case with the normal packages but I have not tried this with Snaps and Flatpaks.

Does it have anything to do with the dbus changes mentioned in this kooha issue?

1st terminal:

pkill flameshot
flameshot
QSettings::value: Empty key passed
QSettings::value: Empty key passed
QSettings::setValue: Empty key passed
QSettings::value: Empty key passed
QSettings::setValue: Empty key passed

2nd terminal:
nothing, but i received a system notification witch says "Unable to capture screen"

Flameshot v0.10.1
Compiled with Qt 5.15.2
Flameshot was compiled from source

@pashtet422 Can you confirm that you are using Gnome and Wayland?

[pashtet422]

Yes, i'm using Fedora 35 with gnome 41.0 and wayland. Flameshot has been crashed after update from Fedora 34 to 35.

[pashtet422]

Upd: i've tried to recompile from source again and a problem still exists

[mmahmoudian]

might be related to #1622 or #675

[borgmanJeremy]

@mmahmoudian I reproduced this issue today on Fedora35, but it works on Fedora34. Given the other report about Gnome41 on arch, I think we should conclude Gnome41/ mutter made a change to the screenshot API.

Edit: I cant reproduce this on Arch with gnome 41....

From fedora:

I can reproduce this independent of flameshot:

Okay, I posted the details on the upstream package: https://bugzilla.redhat.com/show_bug.cgi?id=2009460
