(This bug report unfortunately got no response at the time.)
I can reproduce this bug in Emacs 28:
(set-frame-position (selected-frame) 0 0)
=> t
(frame-position (selected-frame))
=> (-10 . 66)
If I do this, I can clearly see that the frame isn't outside the screen
(i.e., I can see other windows between the Emacs frame and the border of
the screen):
(set-frame-position (selected-frame) 9 0)
=> t
But still:
(frame-position (selected-frame))
=> (-1 . 66)
This is a Debian bullseye system with Gnome Shell.
Anybody got an idea what's going on here?
