After open on-screen keyboard, all of the controls are hard to click.

After i open my on-screen keyboard in some way all the controls are hard to click. I played MCPE on two devices, this happened for both of them. Every version i try is having the same glitch. It's hard to click the right buttons and when i close the game everything is fixed. My keyboard is working fine, when i try to type something. I was searching for fix, but i didn't find anything.
