Tried installing xborders because it was supposed to be a workaround for i3 not having "proper" curved borders. I installed the requirements, even setting up a venv like some others on GitHub did even though the instructions don't say anything about that, only to be hit with this
[arch@archlinux xborder]$ ./xborders --help
Traceback (most recent call last):
File "/home/arch/xborder/./xborders", line 14, in <module>
gi.require_version("Gtk", "3.0")
^^^^^^^^^^^^^^^^^^
AttributeError: module 'gi' has no attribute 'require_version'
The fact that xborders hasn't been updated in 2 years doesn't fill me with much hope either.
