I haven't been on this thread for a while (since they released the minor hotfix for the issue which I didn't install) so have been putting up with the issue waiting for a hotfix on the beta perhaps as I'm running the latest Public Beta 18.1. However I just changed the settings you suggested and I can vouch the same - I can absolutely finger blast the keyboard now and every tap hits!Alright, I think I found a solution that works for now. You don’t have to completely disable the Camera Control button, only the light press and swipe options. To me, this confirms that this is a software issue, because the problem just disappears with this fix.
I also performed the Tinder test (tapping / swiping to the next photo / profile dozens of times) and it now works 100% of the time. Before the fix, it worked about 33%.
I can't say I noticed much lag in other areas - it was the keyboard typing for me, or sometimes tapping a notification or an app. I'll keep testing though as it's only been about 10 minutes 😅
