White Background after compiling

[Arnab-arp]

I am trying to buid a very basic Login and Signup form. I have designed my form on Figma and compiled it using the Tkinter-Designer. The background image that I have used along with all the effects that I have put in using Figma, is not rendering in the final output. Let show you what I am talking about.

This is how It should look like

This is how it looks like after the code generation

Is there a way to fix this
