Public bug reported:

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.
