SUMMARY
I have been having this problem seemingly randomly, sometimes it happens and sometimes it doesn't, and I finally got a way to reproduce it. 

It has also been reported in the reddit community. However the author apparently didn't create an issue here.
https://www.reddit.com/r/kde/comments/mb5tdi/what_are_these_borders_they_only_appear_on_gtk/

STEPS TO REPRODUCE:
1. Disable the title bar in firefox (hamburger menu -> customization -> title bar checkbox, at the bottom of the window)
2. Create a kwin rule for the firefox window and under Appearance and fixes select "No title bar and frame". Set the Force option and check "No".
3. Open firefox

Although I tested in firefox, this worked in every GTK application I have installed.
