SUMMARY The Bounce Key settings under System settings > Accessibility > Keyboard Filters is not working. Repeated keys do not get eliminated and the bell ring does not sound. STEPS TO REPRODUCE 1. Activate Bounce Keys under Accessibility > Keyboard Filters 2. Activate Ring system bell when rejected 3. Quickly tap a specific key OBSERVED RESULT Repeated keys do not get rejected and no notification sound is made. EXPECTED RESULT Thee second repeated key should get rejected and a system bell notification sound should be made alerting that the system rejected the repeated key. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora 38 (available in About System) KDE Plasma Version: 5.27.8 KDE Frameworks Version: 5.109.0 Qt Version: 5.15.10 ADDITIONAL INFORMATION I have used KDE for years in my laptop and I've always had an issue when typing fast I will get repeated keys randomly. I managed to "fix" this issue by making a custom script that will modify xkbset and allow me to set Bounce Keys to 20ms. However, xkbset does not work in Wayland. I tried activating the Bounce keys setting under accessibility but no matter what ms I write it doesn't filter the repeat key. This makes KDE very hard to use specially for coding. I've had the same issue in Kuubuntu 23.04.

Bounce keys are not implemented on Wayland. This needs an implementation similar to what I did for sticky keys: https://invent.kde.org/plasma/kwin/-/merge_requests/3365

X11 had the cap at 50ms which was still too high. Thanks.

Implement bounce keys on Wayland Bouce keys suppresses additional key presses during a given interval This is used by people with motor impairments or bad keyboards It works by remembering the last input timestamp for a key If an event's timestamp is too close to the last timestamp for that key the event is rejected M +1 -0 autotests/integration/CMakeLists.txt A +127 -0 autotests/integration/bounce_keys_test.cpp [License: GPL(v2.0+)] M +1 -1 src/input_event.h M +1 -0 src/plugins/CMakeLists.txt A +18 -0 src/plugins/bouncekeys/CMakeLists.txt A +55 -0 src/plugins/bouncekeys/bouncekeys.cpp [License: GPL(3+eV) GPL(v3.0) GPL(v2.0)] A +28 -0 src/plugins/bouncekeys/bouncekeys.h [License: GPL(3+eV) GPL(v3.0) GPL(v2.0)] A +32 -0 src/plugins/bouncekeys/main.cpp [License: GPL(3+eV) GPL(v3.0) GPL(v2.0)] A +5 -0 src/plugins/bouncekeys/metadata.json https://invent.kde.org/plasma/kwin/-/commit/e7942c3485f332f478be23040e2f0a3b7ed12cb6
