<Snipped quote by Mahz>

Redactor has a very annoying tendency of popping into and out of existence when scrolling on a mobile device. Both tend to appear at the top of the screen at all times, creating a bit of an irritating flickering. Redactor has more features, but Froala has the features it includes implemented smoother.

Got the same effect on Redactor. Redactor was a bit annoying with its pop in and pop out from the scrolling, and adding of a new line that would scroll the page upwards would also cause flickering. 

Froala didn't have the flickering issue, but you mentioning that appeared at the top of the screen is interesting cause mine appeared at the bottom and covered the last line of edited text.
