my brother asked to help fix his nuphy air75, reporting 'weird inputs whenever i type fast' i found that whenever i type at around anything around more than 80wpm~, and press space (sometimes other keys but most consistently with space) a bunch of random inputs are sent, sometimes its everything on the first row, sometimes its some random function keys, i cant decipher any rhyme or reason to this. this issue happens over different os (linux, windows, and mac) and over differenct connections (wired and bluetooth). the keyboards firmware is up to date, all the switches work in my keyboard, the pcb isnt obviosly damaged, and i just cant figure out what the problem is. is my brother just playing a weird prank to drive me insane? or do i just need to buy a new pcb. pls help i feel like im going crazy
