Troubleshooting

The terminal plugin does not work or launch gnome-terminal

To locate your default terminal pop-launcher uses debian alternative. You will need to symlink your favorite terminal to /usr/bin/x-terminal-emulator to have pop-launcher detecting it.

Transparency does not work

You are probably running onagre on wayland, unfortunately transparency is not yet supported with vulkan backend. That said you could make this work using opengl backend running WGPU_BACKEND=gl onagre if you do so transparency should work but onagre won't render icons anymore.

Icon are not rendered

You need to run onagre with vulkan to have the icon show up. Normally this should be the default behavior. Try to run WGPU_BACKEND=vulkan onagre, if it's still not working you probably need to install vulkan on your system. For instance on archlinux with an AMD GPU install the vulkan-radeon package.
