did you notice anything else behaving weirdly when resuming? usually the timer offset error is caused by X being overloaded and not calling libinput_dispatch() often enough. If you notice slow rendering and general delays during that time, then it's most likely not a libinput bug.
Youre right, high CPU of kworker process. Thanck you
