New lineage-19.1 builds has increased touch polling rate feature. Try using that. Settings-> Display -> High touch polling rate
Sry to blast your dms too just trying to make sure you'll see:
Touch polling fix is pretty nice and it alleviates lot of issues with the touch but sadly it doesn't fix the underlying issue with it -the touch recognition is skewed. Touch itself feels "alien" lol
I explained in dms like this:
I managed to figure out what's going on this time and it's not latency issue. It happens when you put your finger on the screen and hold it in place for a really really short time - like 200ms or less (0.2s)
Once you start moving finger after that short hold the touch recognition goes bonkers and tries doing a skewed swipe:
In pics above you can see what's going on - I am 100% sure it's not my finger moving at all. I only hold it in place for a short time then try to swipe up and this happens...
In daily use it is noticable during swiping/scrolling - and only happens on the initial swipe ! It looks like delayed swipe - as in your finger moves up but the screen is refusing to move for the short duration ( As you can see above most likely it's registering as a short swipe sideways , so that's where the lag is coming from ) then after that delay it starts working properly... Feels like a sluggish swipe - as in first half a second of swipe is not responsive then it wakes up and starts working properly
If you're swiping without removing finger at all it's practically impossible to get this skewed swipe to occur, it only occurs in the very first moments of swipe and as you can see in pics it happens randomly
I'll leave my guess here and say it may have to do with touch going to sleep after you lift your finger off the screen , then next time you place the finger back on the screen it ramps up and makes a mistake where touch >hold > swipe up is recognized as touch>hold>swipe sideways>swipe up
Low latency makes it feel less pronounced but it's still happening and the touch itself feels really weird and unnatural ...
