Dwell clicking indicators go behind certain system UI

[1j01]

The screen overlay and thus dwell clicking indicators go behind, on Ubuntu 22, the launcher's window picker (when switching between two or more windows), as well as the Activities screen, and any context menus.

It can be quite jarring when it clicks suddenly without any indication that it's going to (whereas normally it gives you a fair warning.)

I'm already setting the window to always on top and specifying the highest level available, "screensaver", but I could try periodically bringing the window to the front (without taking focus), or research system APIs to do this.
