UI components flashing on the screen.

[Ma5t3rful]

Is there an existing issue for this?

• I have searched the existing issues and found none matching what I'm reporting.

Bug Description

UI components are glitchy, rapidly appearing and disappearing. Same as #1879 except its not the whole screen.
It's kinda similar to those Wayland bugs in the early days.
It's way worse than what it looks like in the vid:

output_video.mp4

Steps to reproduce the behavior

1. Just open the app on Kubuntu 25.04

Expected behavior

No flashing

Ubuntu release

Other (specify in the last field)

What architecture are you using?

amd64
