Windows version : 22H2
Build number: 19045.2546
The issue occurs since the first time I installed it.
If you want to reproduce it, just plug in three monitors and enable the option to center the taskbar icons. It's random, so sometimes it works on three monitors. But more often than not, it randomly doesn't center on one of the monitors.
Here's a screenshot :
You can notice the righ screen doesn't have its icons centered.
Here you go, hope there is everything!
