Issue/Bug Description/Video Capture/Screenshots

Whenever I open a window it won't tile it, instead it opens it floating.
I freshly installed forge from source using make dev.
Looking at the logs, gnome-shell throws this error: "meta_window_set_stack_position_no_sync: assertion 'window->stack_position >= 0' failed"
I tried downgrading to gnome-shell 50 and 50.1 but I had the same problems.
Thank you for your time.
