Bug#879566: Half-maximized terminal windows not edge-to-edge, size changes with zoom or tab bar

Sun Oct 22 21:18:12 UTC 2017

Package: gnome-shell
Version: 3.26.1-3
Severity: normal

I don't know whether this bug lies with gnome-shell or with mutter, but
either way, it's a serious usability problem when using terminal
windows. I think this might correspond to the changes to support
resizing a pair of half-maximized windows by grabbing the border between
them.

Previously, when half-maximizing a terminal window (with Super-Left or
Super-Right), the window would extend all the way to the edge of the
screen on the bottom and side. Zooming the terminal with Ctrl-plus or
Ctrl-minus would change the font size but leave the terminal
half-maximized, and opening a second tab or closing the penultimate tab
would show or hide the tab bar but leave the terminal half-maxmized.
Showing or hiding the menu bar worked similarly.

Now, when half-maximizing a terminal window, it resizes to an integral
number of character cells, leaving a distracting border on the bottom
and the right side. And when zooming, or showing or hiding the tab bar
or menu bar, the window size changes, often pushing part of it
off-screen.

For that matter, opening two terminal windows, half-maximizing both, and
dragging the border between them produces various buggy behavior with
window borders jumping around and separating. I think the whole
mechanism doesn't work well with windows that have resize increments
other than one pixel.
