Keyboard language switch lag, a long standing issue that never gets fixed.

The keyboard language switch button, whether it's a dedicated button or the classic cmd+space, lags unpredictably. Sometimes it works fine, sometimes it doesn't work and takes four times for the input to go through.

No, this is not a "Have you added language preference to your Language&Region settings issue. I obviously have.

If this is a "It's because the shortkey has two different bind depending on whether u long press or short press" issue... Then there's nothing to be done about it anymore since in Ventura it doesn't let you customise your language switch keyboard shortcuts. But I've tried karabiner to get around this and the issue still persists no matter the configuration.

I've used apple macs for decades and this has been a problem for every device, for every OS update. I'm pretty sure this is because non-romance language bilingual users are not a priority for Apple.
