Input has short blink when you focus on it

Hi there
I faced one serious bug when I was working on making layout for my app.
So when I focus some input (only on iphone devices/emulators/emulators in chrome), I see some blinks
I think this is connected with css property pointer-events, which is set to “auto”. Is there any way to fix this ?
I’ve attached screenshot so you can see the bug

Thanks in advance
