Sometimes when typing there's an issue when typing the same letter more than once where it keeps doing the same letter until the letter is pressed again. e.g. I want to press 's' a few times, then when I stop pressing 's' it'll keep doing 's' even if I'm not pressing until I press 's' again*, even if I press another key. *(pressing the same direction to stop going in that direction is not the instinctive thing to do when playing a game)
The times I've gotten it to do this in a plain text editor, it when like this: I press 't' it shows 't' fine it, and it works like this fine for a while, then at some point, it only shows up every other time I press 't', up until some point where it switches to keep doing 't' until the key is pressed again.
It goes something like this:
starting from having pressed 't' a few times already.
input -> output
t -> t,
tt -> t, (extra t pressed, no output change)
ttt -> tt,
tttt -> tt, (extra t pressed, no output change)
ttttt -> ttt,
tttttt -> ttt, (extra t pressed, no output change)
ttttttt -> tttt,
ttttttt -> ttttttttttttttttttttttttttttttttt...ttttttttttt until another 't' is pressed. (the number of keys could be more or less if 't' is pressed again at a different time) (Note: didn't count the number of times before it switches to keep adding the key)
This happens in Windows and Linux, and in several different applications, and with different keys.
Check the keyboard driver and update to the latest version, or update the system, try to use the external keyboard to see if it can be used normally. If it can’t, it means the motherboard is faulty. If the external keyboard works normally, the keyboard hardware may be damaged and you need to replace it .
