AppImage build shows a white window

Upon launching the appimage (flight-core_2.26.2_amd64.AppImage), a bright, blinding white window is rendered.

Running the appimage through a terminal emulator yields the following output:

WARN  arboard::platform::linux > Tried to initialize the wayland data control protocol clipboard, but failed. Falling back to the X11 clipboard protocol. The error was: Unknown error while interacting with the clipboard: A required Wayland protocol (zwlr_data_control_manager_v1 version 1) is not supported by the compositor

** (flight-core:59033): WARNING **: 22:38:08.924: webkit_settings_set_enable_offline_web_application_cache is deprecated and does nothing.
Could not create default EGL display: EGL_BAD_PARAMETER. Aborting...

Tested on Fedora Linux 41, AMD CPU/GPU, Wayland.

Start by reproducing flight-core_2.26.2_amd64.AppImage on Fedora Linux 41 with an AMD GPU under Wayland, launching it from a terminal to capture the EGL and WebKit output. Investigate the desktop rendering and AppImage startup path; done means the window renders normally in the reported environment and the relevant build or launch validation succeeds.
