I tried this on a clean-install of Fedora 43 KDE Plasma it works:

I will try to install Gnome version and will update this post.

[rlabrach]

Yes thanks, I'm using a fresh install of fedora 43 on my side.

I couldn't reproduce this on Fedora 43 Gnome either:

[rlabrach]

argh... i have always this in the terminal... flameshot: info: Capture d'écran sauvegardée sous /home/renaud/Images/2025-11-05_14-54.png QThreadStorage: entry 2 destroyed before end of thread 0x55a4fe388d90 QThreadStorage: entry 1 destroyed before end of thread 0x55a4fe388d90

[rlabrach]

i use a fresh install of Fedora 43/Gnome on an another computer, I have the same problem... How do you think I can move forward with my problem? Thank you.

[mmahmoudian]

Perhaps I've misunderstood your issue. So you can run flameahot gui and you can take a screenshot?

[rlabrach]

Yes, i can run flameahot gui using the terminal, but it doesn't work when I click on the program icon, nothing happens at all. When I use the flameahot gui command, the program works fine and I can save the screenshot, but right after that the program quits on its own and the terminal displays :

[borgmanJeremy]

Can you post your config file?

[rlabrach]

Please, tell me how i can send it to you.

You mean this ? :

[General] contrastOpacity=188 disabledTrayIcon=false showSelectionGeometryHideTime=2998 startupLaunch=true

[rlabrach]

maybe it's better in english ;)

[borgmanJeremy]

The config file you posted was perfect, want to make sure we try to replicate with all the same settings

[rlabrach]

The strange thing is that I just installed Fedora 43 / Gnome on another machine (Framework 13 / AMD) and I have exactly the same problem... Could this be because I am using a French version of Fedora?

[borgmanJeremy]

You could try testing in English or testing the flatpak to help isolate the difference.

I can set up a French fedora VM to see if I can replicate it that way.

[rlabrach]

Hello, I tested both the RPM and Flatpak versions with the same result: neither of them launches directly. I have to go through the terminal.

[Darahz]

I have the same issue on Ubuntu 25.10 running gnome 49, which was updated recently.

[rwxjon]

Hello! I have the same issue, i have updated to fedora 43

[mhagnumdw]

FYI:

• I installed Fedora Workstation 43 with Gnome 49 in a VM (Gnome Boxes).
• I fully updated the system and restarted.
• I installed flameshot via dnf.
• The command flameshot gui did nothing.
• The command flameshot launcher made Gnome open the popup to allow screen capture.
• Now flameshot gui opens, I can select an area, but it doesn't copy the image to the clipboard (via Ctrl+C or the copy button).
• I restarted the system.
• Everything repeated itself, except for the popup to allow screen capture.

This was the behavior I experienced. If you want, I can perform more tests.

[rlabrach]

Thanks mhagnumdw, Does the application launch correctly from the applications menu?

[mhagnumdw]

@rlabrach, I just performed the test:

• I started the system
• There was no instance of flameshot running, ok (I checked with ps aux)
• I clicked on flameshot via the gnome menu (as in your image above)
• flameshot ran in the background (without a GUI, I checked with ps aux and trayicon)
• In the terminal I executed flameshot gui
• The flameshot selection GUI appeared correctly, but the problem of not copying persists

$ flameshot --version
Flameshot v13.3.0 (-)
Compiled with Qt 6.10.0

[borgmanJeremy]

@rlabrach do you have a gnome extension to enable the tray icon? I can't replicate your issue yet, but was wondering if it was something simple like that.

[rwxjon]

I tested the GNOME extension AppIndicator and KStatusNotifierItem Support, and I can see the icon in the taskbar with its options. However, when I click “Open Launcher”, an error message appears in the notifications area, along with the frame for taking a screenshot. If I click the “Take Screenshot” button, the same error message shows up again in the notifications.

[mhagnumdw]

@rwxjon , for me too. Right-click on the Flameshot icon in the system tray, then select the Take screenshot option.

I’m also experiencing the same issue

Environment:

• OS: Kali Linux Rolling
• Desktop: GNOME 48.4
• Session: Wayland
• WM: Mutter
• Flameshot fails with: “Unable to capture screen”
• App does not open or capture any region at all

It seems to be a GNOME + Wayland–specific regression, because the exact same setup was working before until something happened recently which still unknown to me, As per the above comments this might be speicific to Gnome

[MichoGames]

Well, I was able to run it through a keyboard shortcut using the command: flatpak run --command=flameshot org.flameshot.Flameshot gui in the keyboard shortcut settings, then I granted permissions: flatpak permission-set screenshot screenshot org.flameshot.Flameshot yes; however, it doesn’t let me copy the image to the clipboard.

[godly-raam]

An Extra detail:

Flameshot works only when launched from the terminal. Running flameshot gui via CLI lets me capture the screen normally

However, when I try to use any Flameshot keyboard shortcuts , it fails and the application freezes

Above screenshot taken thorugh Flameshot but with the flameshot gui command

[verils]

I thought it was only me who had this problem.

This happened on Fedora 43 with GNOME 49 and QT6, which is running on my host machine. The result is, I can take the snapshot but can not copy anything to clipboard.

But in the VM running a fresh Ubuntu 24.04 on the same host, it worked, and the picture was successfully passed through!

News:

It may relates to this issue: #4363. I'll verify again when it's fixed.

[rlabrach]

Yes same problem with Appindicator

But it's work when start from terminal...

[cjspd-oly]

Fedora 43 Workstation Gnome - Downloaded like 2 days before.

I am also facing same issue on English version. Also, Copy to Clipboard not working.

From Terminal it works. But fails when i do from flameshot app icon. $ flameshot gui QLayout: Attempting to add QLayout "" to SidePanelWidget "", which already has a layout QPainter::begin: Paint device returned engine == 0, type: 2 QPainter::setRenderHint: Painter must be active to set rendering hints QPainter::setCompositionMode: Painter not active QPainter::translate: Painter not active QPainter::setPen: Painter not active QPainter::setBrush: Painter not active QPainter::drawEllipse: Painter not active QPainter::setBrush: Painter not active QPainter::drawEllipse: Painter not active flameshot: info: Screenshot aborted. QThreadStorage: entry 2 destroyed before end of thread 0x556970c2cd90 QThreadStorage: entry 1 destroyed before end of thread 0x556970c2cd90

[cjspd-oly]

@mmahmoudian This is a common issue. Could you please label this issue again?

[cjspd-oly]

@rlabrach I found a workaround/solution use flatpak. It atleast launches.

Clipboard issue exists on Flatpak
