X11: `backend::create_screenshots` creates blank screenshots

[eneoli]

System also has Hyprland installed.

Steps to reproduce:

• install xorg, xorg-server and xorg-xinit
• install gnome or plasma desktop environment
• Run flakeshot under x11 env.

Related to #88 crop selection bug: canvas not getting cleaned properly because of the screenshots being transparent.

Other screenshot tools are able to do screenshots seamlessly.

Function did screenshot the whole virtual screen and set them as individual screenshots of the screens. Partially fixed in #88 but screenshots still blank.

[eneoli]

Problem exists on KDE and Gnome only. We will use a workaround via FreeDesktopPortal Screenshot capability.

See this python code for a reference implementation
