Copy via clipboard only working to some applications

[CEHitchens]

Flameshot Version

Flameshot v12.1.0 () Compiled with Qt 5.11.3 (The same phenomenon with the Linux Mint's 21.2 Cinnamon repository version, which made me get the *.deb from https://github.com/flameshot-org/...

Installation Type

Using the ready-made package from Github Releases

Operating System type and version

Linux Mint 21.2 Cinnamon

Description

Pasting a Flameshot screenshot into Signal messenger is not working. Pasting via the clipboard also doesn't work to websites such as imgur.com using Mozilla Firefox, LibreWolf and Vivaldi (yes, I know about Flameshot's built-in imgur upload function). Those used to work without any issues before, i.e. Linux Mint 20.3 Cinnamon.

What does work, though, is pasting to GIMP, Pinta, Thunderbird, LibreOffice.

Cinnamon desktop notificaitons are enabled and I do see a notification that Flamshot copied something to the clipboard. However, as said above, it only works with some 'destination' applications.

In other issue reports on here I saw mentions of enabling/disabling "use jpg format for clipboard option" somewhere. I don't have such an option. The only thing that I found coming close to that is setting file formats on the "General" tab > "Save Path" section. I tried it with jpeg and png.

This issue may be related to #3107, also using X.Org, but KDE instead of Cinnamon.

Steps to reproduce

1. Flamshot is being launched with "flameshot gui"
2. Select area
3. Click the copy to clipboard icon (these two overlapping sheets) or use ctrl+c
4. Desktop environment notification informs that Flameshot copied something to the clipboard
5. Switch to Signal messenger, Firefox, Librewolf, Vivaldi and visit imgur.com
6. Use ctrl+v to paste, which should create a new post
7. No paste happening
8. [Pasting to GIMP and Pinta first, then performing another ctrl+c from there to then paste to Signal messenger, Firefox, LibreWolf and Vivaldi works]

I am also facing the same issue, but in my case, the copy to clipboard feature is not working. I am using Flameshot on Arch + i3.

[The-Compiler]

The copy to clipboard functionality started to break today for me on Arch as well (mostly tried with Discord). Weird. Worked fine before!

Can't really see any changes here that would be relevant: Commits · kde/5.15 · Qt Project / qt / qtbase · GitLab

[graevy]

also experiencing this on arch

Im expriencing the same issue, but its weirder that it would froze once I press Ctrl+C or the copy button.

I have tried to reinstall it or deleting the configuration file, and did a clean install still wouldn't work.

I found it while using the flameshot status tray icon to copy it, and it wouldn't copy it and the icon none functional for a couple of seconds. Im using OpenSUSE Tumbleweed, x11, KDE Plasma.

Facing same issue and came here to see if someone fixed it. Apparently not. I can only paste the image in Telegram but other apps like Google Chrome, Dicsord, etc can't recognize anything in my clipboard. Moreover, I checked Windows Key + V nothing in the clipboard history as well.
