Can you reproduce your problem when you restart ibus-daemon? (yes / no):
yes

Do you see any errors when you run ibus-daemon with the verbose option?:
(ibus-extension-gtk3:49862): IBUS-CRITICAL **: 18:23:34.920: ibus_emojier_update_category_to_emojis_dict: assertion 'data != NULL' failed

Other steam users seem to be getting the same issue: ValveSoftware/Proton#5294 Except it isn't at low FPS.

Arch 6.2.2-zen1-1-zen with ibus-daemon - Version 1.5.28 with X

Experiencing the same issue in all proton / wine apps, WASD keys or others that are pressed for continued amount of time cause it to never stop and you start moving in one direction indefinitely until you let go and press the key a single time, acts like a stuck key. This issue did not seem to be present until this version.

Also superficially similar to #2081, and thus ValveSoftware/Proton#5294 as well.

Seeing the same on Fedora 38. Downgrading to Fedora 37 fixes the issue.

Fedora 37: ibus-1.5.27-5.fc37.x86_64 - not affected
Fedora 38: ibus-1.5.28-1.fc38.x86_64 - affected -> killing ibus-daemon (killall ibus-daemon) fixes the issue for the current boot
