@ITwrx it's probably an incompatibility with Wayland, I don't think many (any) body is using that. Are you able to startx and try and reproduce in X11? Those warning message's you're getting are related to the window/desktop manager.
@elextr i don't know what you're asking for with "can you post a gist of your user config".
He means to [pastebin](https://gist.github.com/) the file `~/.config/geany/geany.conf`. It contains filenames, which may include your username or such (ex. recent file `/home/you/topsecret/hitlist.txt`).
