Can someone please acknowledge this?

I could not reproduce it on my system. Perhaps something is strange with your dpi/resolution?

In any case, filechooser is a pretty old widget in serious need of overhaul. May I suggest plyer's native file chooser? I switched to it recently and it was much better, given it's using the OS's built in file browser.

Thanks Matham will give plyer a try.

Matham's solution was much more elegant and works perfectly, hence closing this issue

If someone is still searching for this in the future - the bug comes from loading your kv file twice using Builder.load_file and name convention. Remember that kivy also automatically searches for a kv file based on your app name, ie if you name it EditorApp, kivy will search for editor.kv.

To fix this simply rename your kv file into something else or remove the Builder.
