FileNotFoundError due to the file path wasn't decoded for UTF-8

[supersonictw]

What happened?

Not to decode file:// scheme URL characters for regular UTF-8 characters will cause FileNotFoundError.

Tried running from:

• pipx
• flatpak
• appimage

Solution:

It might should be fixed with:

# In "normcap/screengrab/handlers/dbus_portal.py", function "_synchronized_capture".
    uri = result[0]
    parsed_uri = urlparse(uri)
    parsed_path = unquote(parsed_uri.path)

    image_path = Path(parsed_path)
    image = QtGui.QImage(image_path)

How did you install NormCap?

Python Package (pip install)

Operating System + Version?

Debian 12

[Linux only] Display Server (DS) + Desktop environment (DE)?

DS: Wayland, DE: KDE Plasma 5
