Hello Nate,

I'm reopening this because today I took some time to boot a neon-testing live
medium and reproduced easily.

The key aspect seems to be: dual screen setup + fractional scaling.

System info:

Operating System: KDE neon Testing Edition
KDE Plasma Version: 6.0.0
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.2
Kernel Version: 6.5.0-21-generic (64-bit)
Graphics Platform: Wayland
Processors: 16 × AMD Ryzen 7 7840U w/ Radeon 780M Graphics
Memory: 30.5 GiB of RAM
Graphics Processor: AMD Radeon Graphics
Manufacturer: Framework
Product Name: Laptop 13 (AMD Ryzen 7040Series)
System Version: A7


Issue appears on external monitor (the one on the left) when it is scaled to
100% BUT the integrated one (on the right side) is scaled to 125% (see
attachment).

I could also reproduce with other combinations of scaling.

But interestingly, once I set 100% scaling on both displays, the issue is not
reproducible.

It's as if the 125% scaling of the internal monitor affected the external one.
Also curiously enough, with a 100% scaling for the external + 125% for the
internal, the visual artifact is visible on a context menu drawn on the
external monitor, but if I move the window to the internal display, the
artifact is not visible.

I am not sure if this is KDE/frameworks related, or has something to do with my
GPU/drivers (although I have a quite bland integrated AMD GPU with open source
drivers...)

Thanks and looking forward to the release! <3
