– Top bar spacing issue
– slider Glitchy issue
– other spacing in the homepage

regarding customizer, yes it will show the mobile menu because the customizer parts almost cover 25% of the screen, so preview parts behave as like its a tablet screen. you can Zoom out the screen by pressing ctrl and “-” btn in the keyboard to show full menu
