Input lag on Pixel 2 XL (Oreo 8.1)
I have just bought a Pixel 2 XL a week ago coming from OnePlus 5 running Nougat 7.1.1, and ever since I have installed SwiftKey I notice input lag very often when I'm typing. It will go away for a short while then come back when I'm typing. It's very sporadic and unpredictable. I'll be typing normally and there will be no lag whatsoever, but suddenly as I type there will be a slight pause and lag before the word is completed.
On my OnePlus 5 I had no such issues and suddenly it's getting very irritating on my Pixel 2 XL which is supposed to have the best software experience of any Android device. So I'm not sure why it's happening.
I have tried clearing SwiftKey app cache and it doesn't seem to help. Has the app not been optimised for 8.1 yet? I have been using SwiftKey for at least 7 years now and not had this particular issue in input lag.
