Few things i thought of, after testing 1-2 weeks on Fedora 42 Wayland kde.

Hi, after the update to fedora 42 kde, spectacle turned into something i didnt like,

Got suggested to use flameshot, so i installed it.

What i have noticed/struggled with:

Shortcut:
"Accept the capture" [Enter] - does not work, nothing happens when i press enter
"Copy selection to clipboard" [Ctrl+C] - Lets thru the keystroke to what ever application is next in "z index"
"Save screenshot to a file" [Ctrl+S] - Lets thru the keystroke to what ever application is next in "z index"

Is the "Accept capture" supposed to function similar to Spectacle, that after accepting the screenshot/selection, to put it into a window where i then can add arrors or something, and let the rest of the display return to show what ever its doing?
Sometimes i want to snap something quickly, add arrows or something, but it "stops" videos until im done editing the screenshot (it keeps the fullscreen images i snapped from)

@VinterSolen thanks for giving Flameshot a try. There are a few fundamental points that you got wrong and I'll try to explain here:

Is the "Accept capture" supposed to function similar to Spectacle, that after accepting the screenshot/selection, to put it into a window where i then can add arrors or something, and let the rest of the display return to show what ever its doing?

No. The "Accept Capture" is only functional when the user has defined the "final actions" through the CLI (explanation about Final Actions). So if you run flaneshot gui then Flameshot doesn't know what should it do with the picture. So pressing Enter is ambiguous and the user have to decide the final action by pressing the corresponding keybinding such as Ctrl+c to Copy or Ctrl+s to Save. Alternatively user can run flameshot gui --clipboard --path="blah.png" --pin, so that when pressed the Enter, Flameshot does all those final actions on after another.

Sometimes i want to snap something quickly, add arrows or something, but it "stops" videos until im done editing the screenshot (it keeps the fullscreen images i snapped from)

When you run flameshot gui (or click on the tray icon), Flameshot would ask the compositor (in your case Kwin) to take a screenshot and then pass it to Flameshot. Upon receiving the screenshot, Flameshot would display it as an overlay on your monitor so that you can select the area you are interested in using your mouse, and you can then annotate it (arrow,...). That's the reason the video seems like "stopped". It is because the screenshot is taken immediately when you run Flameshot and then it is a static image that you can annotate to your liking.

Lets thru the keystroke to what ever application is next in "z index"

I don't understand what you mean by this, but if the Ctrl+c or Ctrl+s is not passed to Flameshot, it can be because your window manager has put Flameshot out of focus. Although I'm a KDE user myself and I've never experienced it.

To compare to spectacle, after i pressed print screen, it over lays just like flameshot, then i can crop a selection area, and press enter to accept the area, and then in a seperate window, i can modify the screenshot i just snapped, where as the overlay, is gone and stuff like the video shows normally again. Where as on flameshot, it keeps the overlay until i ctrl+s or ctrl+c the cropped area

Flameshot recieves the ctrl+s/c, but its also passed down to the program that is next under flameshot, so if i want to screenshot a select area in the browser: print screen -> drag crop area, press ctrl+s. Now the browser shows the save dialogue also, at the same time flameshot shows its own save dialogue.

This does not always happen, but the ctrl+s/c gets passed off to the next program when the fullscreen stuff is gone

Correct. This is a new addition to Spectacle in 2025 and Flameshot had this since inception in 2017. Also, this is the design of Flameshot that you all your annotations within the overlay, so that the Flameshot itself is completely out of the way. We believe there is no point in annotating outside of the overlay window, or if user wants, they can take it to another software like Inkscape. There are discussions to add a windowed mode, but for now it is not in the todo list.

That said, you might be more happy with Ksnip that has similar annotation features as Flameshot and is also GPLv3 licensed project, but the annotation is done in a windowed mode. Ksnip development is lead by @DamirPorobic who is a great developer and their project is actively maintained.

That's not the issue with Flameshot but rather your window manager. In Wayland Flameshot cannot pass a keybinding to another window. Considering that I daily-drive Plasma, I'd say it is most probably because of some modification you have done to KDE Plasma that the Kwin passes keybinding to two applications at the same time. It is also possible that your keyboard is sending the keybinding multiple times, and the first one goes to Flameshot, and the subsequent ones go to the next active window. This for example can happen with mechanical keyboards with Hall Effect keys with a very shallow actuation point (e.g., Wooting HE keyboards), although in that case i'd say the problem is not with the software or hardware, but rather the bad configuration.
