One of the only things I dislike about EU MIUI (I'm under 7.3.30, but this was true for other 7.x.xx versions I tried, weekly and stable) is that the capacitive buttons at the bottom aren't 100% responsive. The home and back buttons works OK, but there's a noticeable 1 second lag for the 'recent' button which is very annoying. I've tried LineageOS and Resurrection Remix and there the buttons are much faster.
Are the capacitive buttons responsive and does the recent menu pop uo virtually immediately with no lag on the multirom?
