For many years I've assumed that the subject issue, described below, was
a flaw unique to my particular monitors, a succession of iiyama models,
always 1920 x 1200, my preferred resolution.

But I was wrong, because I've just replaced my 24" iiyama Prolite
E2403WS with a 24" Dell U2415 ...and it has exactly the same bizarre
behaviour. If I maximise any window (an application, a folder, whatever)
its size becomes 1936 x 1186 and its position -8, -8.

I use two utilities to report window size/position: AHK Windows Info
1.7, and Macro Express Pro. But I expect there are many more.

Perhaps it only happens with 1920 x 1200 screens? Anyone able to try it
with the more prolific 1920 x 1080 please?

Any insights as to why this occurs? If others with a screen of any
resolution cannot reproduce, what obscure setting of my setup could
cause it?

What happens if you change the borderwidth setting ?

I checked my other machine here, and it basically does
the same as yours. I run 1440x900, and if a window is
maximized, some of the border is outside the screen
area (could well be -8,-8). But not enough border,
that the "X" isn't fully visible. It's like they
still respect the decorations.
