z-fighting phenomenon of floating windows set to shown_on_top

[Giresharu]

Sometimes I find that floating windows set to shown_on_top exhibit a phenomenon similar to z-fighting in computer graphics—except that in graphics, z-fighting is pixel-level, whereas with floating windows, entire windows repeatedly compete with each other to be on top.

I’ve seen a similar always-on-top feature in PowerToys, and it has no z-fighting at all: whichever window is activated comes to the top (provided it’s set to always-on-top).

However, I don’t know if there’s a CLI command to trigger that PowerToys feature, so I’ll set that aside for now.
Does anyone know of other solutions?
