This app replaces Windows 10's volume pop-up with a custom one that lets you adjust both the position and timeout. It's not completely a solution to what you want since it replaces the default volume pop-up with a different design, but at least it's better than nothing.
Yes it is due to a bug in past 2 Dev builds that I have noticed at least.
I use ModernFlyouts so I see it up top of screen anyhow (the next build is supposed to be a big deal).
It's really ugly and what's worse is it's not consistent with the win11 style, I mean, the rounded corner style... https://github.com/ModernFlyouts-Community/ModernFlyouts this one is much better.
Yes, the way I fixed it was using this.

id recommend ModernFlyouts-Community/ModernFlyouts: A modern Fluent Design replacement for the old Metro themed flyouts present in Windows since Windows 8 (github.com) looks much better than the windows one and you can customize it a bit
