I don't know about others. However, when I am typing quickly, my fingers might 'oh so lightly' brush the Touch Bar, which sends it into some undesirable function. Wondering if a time delay (perhaps 0.3 seconds of a continuous press) is required to activate any of the Touch Bar functions when it is pressed to avoid the issue of slightly touching the bar.
I can relate to this. To fix it, I have a custom setup with buttons that only react to long presses (and some with double-taps as well). To me it works like a charm.
