Noticable Flickering/Undrawn color on Frame when calling destroy

[rebelate]

Hi guys, i stumbled upon a problem, so.. i have a dynamically created button (sit on top of Frame) its created whenever i press a "parent" button, each comes with a different value. i have a needs to destroy and creating a new one based on "parent" button, but when i call destroy on the buttons, there's something like undrawn color like a hole on the Frame. tested on both customtkinter and tkinter below.
any help would be appreciated

Nvm found the solution,
need to specify bg_color to the Frame because by default there isnt any bg_color in the theme json (blue.json)
