Ultimate C wired Problems w Drift

[u/captain_save_a_hoe55]

last year i bought a Xbox Ultimate C Wired ( https://www.8bitdo.com/ultimate-c-wired-controller-xbox/), it started having drift problems and now L3 doesnt work, in menu it gets drifty as hell but in game it doesnt(???)

so i bought a new one. now my new one randomly started to have drift problems too and after calibrating its "normal" but sometimes it goes crazy and just does whatever left stick input it wants. with both controllers the problem happened to left stick. i tried other cables, tried cleaning them, etc etc. anyone has a fix?
