Doesn't work correctly on linux

[RAVENz46]

It works fine on windows(baremetal/vm), however I cannot run on linux. Env: NixOS(Gnome X11/Wayland AppImage-version baremetal) , PopOS(Cosmic/Gnome Wayland AppImage-version vm) , Debian(KDE Wayland deb-version vm)

Bit improvement on NixOS Set Variable:

WEBKIT_DISABLE_DMABUF_RENDERER=1
WEBKIT_DISABLE_COMPOSITING_MODE = 1

Now error says:

It seems doesn't help PopOS and Debian.

Now I realized that it works on NixOS however it's bit wired. It would be preferable to run as a widget like conky instead of window.
