Screenshot of the rendering issues

SUMMARY

I'm experiencing a weird rendering issue in the audio system settings view, specifically in the `Configure` sub view. Text and controls appear "glitchy" with some of the pixels shifted (see attached screenshot, I've highlighted some of the issues). Resizing the window or scrolling can make it more or less glitchy (it visually changes with each Pixel resized).

I'm using no HiDPI scaling.

Apart from the visual issue, everything in that view seems fully functional.

STEPS TO REPRODUCE
1. Open audio system settings view
2. Open the `Configure` sub view

OBSERVED RESULT

Text and/or controls are rendered weirdly as described above.

EXPECTED RESULT

Text and controls are rendered correctly.

SOFTWARE/OS VERSIONS
Linux: Arch Linux (5.11.10.arch1-1 kernel)
KDE Plasma Version: 5.21.3
KDE Frameworks Version: 5.80.0
Qt Version: 5.15.2

ADDITIONAL INFORMATION

I'm using a AMD Radeon RX 6900 XT GPU with the latest AMDGPU driver. A friend with an NVIDIA GTX 1080 Ti GPU and the latest proprietary driver and a very similar software setup (same Plasma/KDE frameworks/Qt version) is experiencing the same thing.
