I have a similar issue on Kubuntu 23.10 on wayland, and swaywm. I compiled from source from latest version using git clone.

Command: flameshot gui

Takes for few minutes to show errors

flameshot: error: Unable to detect desktop environment (GNOME? KDE? Sway? ...)
flameshot: error: Hint: try setting the XDG_CURRENT_DESKTOP environment variable.
flameshot: error: Unable to capture screen
flameshot: error: Unable to capture screen
qt.qpa.wayland: Wayland does not support QWindow::requestActivate()

When I use the suggested environment variable, and flameshot just seems to hang. I added a few environment variables, and I'm in the process of using then in different combinations.

I'm not 100% sure if I understood your issue, but I had something where when I launched flameshot and my desktop would "shrink" to 1/4 of the screen and everything else would be black. If this is your issue, here is how I fixed it.

I'm running Fedora 41 KDE on Wayland, and I installed flameshot with dnf!
This bug seems to be related to the Wayland protocol, so you have to force flameshot to use "XWayland".
Find your menu entry, right click and select "edit"

Look for the location of the app

open a terminal and cd into that location and look for the flameshot.desktop file

edit the file and look for the "exec" line and enter the following

Save the file and restart flameshot.
