Flameshot repeatedly asks for "Use QT_QPA_PLATFORM=wayland to run on Wayland anyway"

[bashfulrobot]

Describe the bug

After the latest update, Flameshot no longer works.

• Shortcut products no GUI, or output
• running flameshot gui at the terminal outputs:

λ flameshot gui
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
flameshot: error: Unable to capture screen
flameshot: error: Unable to capture screen
flameshot: info: Screenshot aborted.

Steps To Reproduce

Steps to reproduce the behavior:

1. Install flamshot from nixpkgs
2. open a terminal
3. Ensure QT_QPA_PLATFORM=wayland is set
4. run flameshot gui

Expected behavior

I would have expected the screen selector to show up so I could take a screenshot.
