Windows 11 Windows 11 Taskbar Glitch [w/ Microsoft Teams] & Covered

Issue #1:
• When I am in a meeting using Microsoft Teams, (not sharing screen), and I move my cursor to the bottom side of the screen under the taskbar; the taskbar pops out and glitches as if I have it on auto-hide mode but without it disappearing.
• It also shows when I am in a meeting, and playing a video game such as GTAV and I move the mouse downwards, the taskbar appears and if I click - it automatically alt+tab me outside the game.

Issue #2:
• In Windows 10 Home, I used to move windows around the screen - but the windows never covered the taskbar. In Windows 11 Home, the windows cover the taskbar that I have to manually minimize everything to get to the window that is covering the taskbar and hide or close it. Is there a way of making the taskbar docked on the bottom side of the screen and make the windows limited to only above the taskbar?
