Title:
gnome-terminal randomly outputs control characters
Status in gnome-terminal package in Ubuntu:
Confirmed
Status in terminator package in Ubuntu:
Confirmed
Bug description:
Observed behavior:
When using tmux, the terminal occasionally displays the "boxed" version of
the 0x001b character followed by two ']' characters either in the cursor's
current location or at the end of a refreshed line, or sometimes at an
apparently random position on the screen. The times at which this character
appears seem to be completely random.
To reproduce:
Get a clean install of tmux and gnome-terminal from the repositories. It is
difficult to quantify this, but it appears that the bug will present itself
most readily when working in vim or another refresh-heavy cli program.
Why it's not a tmux bug:
The bug appears to affect gnome-terminal and terminator, but not xterm or
e.g. sessions connected over putty. In fact, if I open all of these screens
side-by-size (using a virtual machine), and simultaneously attach to the same
tmux session, only gnome-terminal and terminator show the strange characters,
while the other two terminals render the screen as expected.
Please see this superuser discussion for a link to a video of what the bug
looks like:

Let me know if there is anything else I can do to help reproduce/solve
this, as using xterm is a really bad workaround to have to put up
with.
