Hidden elements appear in mobile browsers when scroll

Question

the example below is the method I'm using for my portfolio website.

It's in 'where I live', 'how it began, and 'how I work' in about section and each slider has images and google map. I input the codes as they are in the example in my website except I deleted "overflow: hidden" because it caused black squares appearing and flickering on the screen in Chrome. The sliders are working fine with browsers in desktop computers.

The problem occurs when I use mobile browsers such as safari and chrome in Iphone and chrome in android.

Google map in the "slider" appears on top of the screen even though I didn't open it and the image in "slider3" gets stuck on the screen when I scroll the page after I close it. In mobile Safari's case, it looks okay in the beginning but once I open and close the sliders, they are stuck on top or bottom of the screen when I scroll the page.

I don't get the same problem with "slider2" maybe it's because it's on the side.

Does anyone know why the problem occurs with mobile browsers?

Thanks in advance.
