There is still an issue with the hidden taskbar showing itself early. It's not like it was a few versions ago, though. This is on my primary monitor, and it's not every time. It's very sporadic. This has done it on 2.02 and 2.03 for me. Windows 11 Pro 23H2 22631.2715. If I try to click a tab or something else quick enough it'll activate whatever is in that spot on the taskbar, even before the taskbar itself has actually popped up and is visible. Very random when it happens though.
Using top taskbar, rounded corners, auto hide enabled in start11 and disabled in windows. Pretty sure it behaves the same regardless of where the taskbar is or what it looks like.
Edit to add: It doesn't actually pop itself back up automatically when it does this. It's fully there already, just invisible. Once I actually click the mouse it appears. In my youtube link below I tried to click to close the browser tab, but it popped open the taskbar. It didn't activate any app this time because it didn't happen to be over a pin. If I don't click, I can actually see the outlines of the pins appear as I move my mouse over them.
