Keyboard lag while under load in game

Hello, i seem to be having a weird issue when playing any game that puts my system under load. Any buttons i press on the keyboard appear to be getting queued up faster than they can be processed, so if i press “w” for a while and then let go itll keep acting like im pressing it for a second or so, sometimes even more.
I really have no idea where to start with it, it sounds like it could be something to do with kwin or libinput according to others but havent had any luck finding out what to do.
Anyone know how i would start fixing this?

Kernel 5.12 is EOL so please install both 5.4 and 5.10 LTS (Long Term Support) and see which one of the two troubles you least.

If that would not solve your problem, or if you don’t know how to do that, please shout out!

they both seemed to have the same issue

it is the exact same as yours, i just reinstalled manjaro yesterday

Then you should read this:

especially the section What’s this Upstream / Downstream business? and file a bug with the game developer.

GZDoom on my system works flawlessly and that uses a lot of W too…


GZDoom? Why you talk about this game (or any game to report bug for)? From the explanation this doesn’t seem to be a game bug, but an issue on his system.

@cupiditas How are you starting your games? Is it using the integrated video card or the Nvidia one?

PS: no need to rephrase my posts, thanks.

@omano im using optimus to use both integrated and nvidia, i think all my games start on the nvidia card though.
The only one that i think wasnt was minecraft for a bit, but i had the issue there too for both integrated and nvidia cards.
I am just starting them using the the .desktop for them
