After days of fresh reinstallations and tests, I finally found what was causing this on my end and finally solved it by using a xorg configuration override 10-evdev.conf as shown on [1]
Offender: Gaming mouse driver (Saitek Cyborg R.A.T.9 Wireless Mouse) Driver: libinput After a bit of research, I found that this mouse is known to be malfunctioning with the default settings on Xorg. Despite working at a first look, the default configuration is causing the below symptoms as explained by [2] After being plugged, the mouse will seems to work, but you may experience different issues : * You cannot move windows around when grabbing the window's title bar. (happens with Openbox and other Window manager) * You cannot click on buttons. * You cannot get the focus on windows. * You cannot open menus, even with keyboard shortcuts. * Display does not refresh (using Xcompmgr) * Closing certain windows restores functionality until the mouse locks into a new window.
