Screenshots aren't copied to the clipboard about flameshot HOT 12 OPEN

Flameshot definitely works flawlessly on X11.

Based on your text I think you are not experienced enough with Linux. So here is what you should do:

1. If you are using AppImage, you cannot use flameshot. You have to run that Flameshot AppImage (this is how AppImage works). We have clearly explained it in our documentation ( https://flameshot.org/docs/installation/installation-linux/#appimage )
2. remove the --delay 500, that is not needed, it will just add half a second delay
3. If the above didn't fix the issue, open a terminal and run flameshot (in your case ./ Flameshot-12.1.0.x86_64.AppImage), then open another terminal and run flameshot gui (in your case ./ Flameshot-12.1.0.x86_64.AppImage gui). Then try to copy. It should work

from flameshot.

No, unfortunately it doesn't work anyway.

1. I used the flameshot command because I created a symlink to the downloaded AppImage.
2. Delay isn't in charge, the problem with AppImage is that it seems to exist before putting the image to the clipboard.
3. When I run flameshot gui manually, it works and it does put the image to the clipboard.

P.S. As for experience, I'm just a user, but for like 25 years: Slackware, Debian, RedHat, Ubuntu, Mint etc

from flameshot.
