Q:  11.16.19  10:21 am it's better now, but still lagging, unfortunately. from my testing, if i create a blank file with 3000 lines of identical text it works fine, at 4000 it starts to misbehave (it seems to have more to do with the number of lines of text than the page height)  to be clear, this is not an issue with your website, this is an issue with google chrome for android. even edge for android (which uses the same exact browser engine) doesn't have this issue. i will see if i can notify google
A: try it now, it's less than 3000 lines now
