Flameshot aborts on Wayland/GNOME

Help
21

The reason I use it from Terminal is for testing, I was planning to have a custom shortcut for flameshot, which appears to run the command flameshot gui. Moreover, I wanted to see the logs if anything happens while using from Terminal.

Can you confirm that flameshot gui command works for you?

To clarify, it’s not that I have an issue with running it from Terminal. It’s more that I would expect that to work, since majority of the issues with Flameshot on GNOME are about it failing to launch via shortcut/tray icon and/or not saving to clipboard. In comparison, evoking the app from Terminal would launch properly (not necessarily copy though).

As for your question, it does work for me, a recent log:

[nix-shell:~]$ flameshot
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::translate: Painter not active

QPainter::setBrush: Painter not active
QPainter::drawEllipse: Painter not active
flameshot: info: Capture saved as /home/kibter/Pictures/2025-12-18_11-26.png

I made changes locally since then; found a commit was merged upstream, which properly addresses failure to copy a screenshot to the clipboard on GNOME. The fix combo is a bit convoluted, but it works on my side. I can describe the steps here.

Thank you for assisting, I will try out later tomorrow(UTC + 5). I’m demotivated to continue right now.

UPDATE.

I got it working but under certain circumstances. I came across this reddit post:

In the comment section a user called uguisumaru said:

You can use Flameshot under Wayland.

  1. Install Flameshot via Flatpak

  2. Run flatpak permission-set screenshot screenshot org.flameshot.Flameshot yes to allow Flatpak Flameshot to take screenshots

  3. Run flatpak run --command=flameshot org.flameshot.Flameshot gui to check if it’s working as intended.

  4. Bind a keyboard shortcut for flatpak run --command=flameshot org.flameshot.Flameshot gui via GNOME Settings.

It triggered the UI, I believe I had the moment I could trigger that myself but copying was a issue, it still is. But I have found a workaround to copy the images. In gui mode, there is a Pin button, after clicking that button it just shows the image in Windows, I opened a menu using right click on the image and used Copy to clipboard, which finally worked without crashing.

I’m assuming it’s a problem with permission to clipboard or something like that, but I’m not sure. Thank you everyone who tried to help me in this process.
