Taskbar obscuring bottom of application window across all my Win10 PC`

I`m experiencing some odd behavior on the task bar which I`m trying to work out if its an issue introduced by a windows update, or my own behavior.

The task bar is obscuring the bottom of my full screen application windows. I`ve fiddled with the task bar settings, and I cannot return to a consistent behavior, which allows a maximised window to sit "on top" of the task bar - full screen application windows seem to want to "sit behind" the task bar meaning that the bottom portion of the window is hidden behind the task bar.


I`m seeing this across all my Win10 PC`s - and that makes me think that either I`m syncing these settings across or its common UI bug.

Could someone point out what settings should be applied to force windows to sit on top of the task bar?

Hi, this older thread has two or three suggestions if you scan all the way through:
How do i disable always on-top taskbar ?

Many thanks. Last night I took a cumulative update for 1903 and also installed 1909 and after those installs completed, the taskbar is behaving itself again.

I can only assume this is a bug - I`ll mark this as solved.
