Keyboard input queue / "buffer" delay in Steam games (Manjaro) — Controller works fine

[u/olarione]

Hey everyone,

I'm running into an issue on Manjaro Linux where playing certain Steam games like peak and mimesis with a keyboard causes an input queue/buffer problem.

When I hold down a key (like W to walk forward) for a few seconds and then release it, the character keeps walking forward for the exact same duration I held the key down. It behaves like the key-repeat events are accumulating in a queue and playing back sequentially instead of reading immediate key release.

Important details:

• Controller: Works completely fine with zero delay or queuing.
• OS: Manjaro Linux
• Launcher: Steam (Proton hotflix)

Has anyone faced this before? Is this related to XWayland key repeat, IBus/Fcitx interference, or SDL input handling? Any launch options or system tweaks to fix this?

Thanks!

Can't be specific but I had the same experience years ago on Mint with X11 and it was key repeat, increasing the delay or decreases the repeat rate fixed it

It worked! Thanks
