Bug#940572: gnome-terminal: changing font size on one tab has effect on other tabs

[Ansgar Burchardt]

Package: gnome-terminal
Version: 3.34.0-1
Severity: minor
Tags: upstream

Changing the font size in one tab has an effect of other tabs: when
switching from tab A (with larger font size) to tab B (regular font
size), I can see that tab B gets restored with the larger font size
and is only then changed to the normal font size.

This causes screen refreshes which is noticable when, for example,
running irssi over a SSH connection in one of the tabs.

It would be nice if gnome-terminal would switch font size at the same
time as changing the terminal emulator's contents to avoid such
artifacts.
