Windows 10: Moving mouse off of a window has no effect

I'm having this problem on two Windows 10 computers, so I'm not sure if it's "intended", but here goes.

When I mouse over a window, I can hover and get the normal tooltip. If I move the mouse off of the window where a hover action extends all the way to the end of the window, Windows doesn't recognize that the mouse is now off of the window and will keep the tooltip open. This is very frustrating as I have to put my mouse back on the window and specifically move it off at a place that doesn't have a hover action.

The best example I have is the toolbar options in the top-right corner of any window (minimize, maximize, close). The X turns red when I hover, but if I move the mouse entirely out of the window when it was over the X it stays red because Windows still acts like it is hovering there.

Is there anything I can do to fix this so that Windows recognizes when my mouse isn't actually over a window anymore?

Snap issue

I've purchased a new mouse which even though has the same DPI as my last mouse it triggers the window's snap to edge feature whenever I try to move a window between screens, I don't use the snap feature so I tried disabling it however it also disables the
ability to drag maximized windows which is just as infuriating. I've also tried adjusting the settings in the registry to no effect.

Sound volume bar overlaps EVERYTHING -- how do I get rid of it?

I don't know if it sheds any light on the problem, but if I use the mouse or my finger on the touchscreen to move the volume bar down, it moves itself back to 100%. That has no effect on the lack of audio; the computer remains mute.

Also, further info is that there is no audio icon on the taskbar.
