Printing [2 q in command prompt

[wamoyo]

• nvim --version: NVIM v0.2.1-dev
• Vim (version: 7.4) behaves differently? Yes. Behaves normally.
• Operating system/version: Ubuntu 14.04
• Terminal name/version: Gnome Terminal 3.12.3
• $TERM: xterm-256color

Steps to reproduce using nvim -u NORC

nvim -u NORC
:

Actual behaviour

Prints �[2 q to the command area at the bottom, as in photo...

Expected behaviour

Prints just the : with a blinking cursor as usual when expecting user to enter command.

Also, it prints that �[2 q in random places when pressing Esc, and does weird things when highlighting lines. I can't tell what's wrong. My editor seems drunk : )

Looks like your terminal doesn't support cursor shaping. Newer versions of gnome-terminal do.

We try to detect this via VTE_VERSION, may it's empty in your env for some reason.

To disable cursor shaping, see :help guicursor. It's enabled by default because it's 2017.

[wamoyo]

Woohoo! That sounds solvable : )

$ echo $VTE_VERSION
3603

[justinmk]

Arg, this is a regression. The VTE version check for cursor shaping was removed in the recent TUI rework.

Anything I can do to help?

[justinmk]

If you can try #6997 that would help.

[wamoyo]

Hmmm... Not really sure what to try from that issue.

Put "\x1b[%p1%d q" in set guicursor=?

Hello, I have observed the same bug since I updated nvim. Only a few differences on my system (terminal and VTE versions)
nvim --version: NVIM v0.2.1-dev
Vim (version: 7.4) behaves differently? Yes. Behaves normally.
Operating system/version: Ubuntu 14.04
Terminal name/version: Gnome Terminal 3.6.2
$TERM: xterm-256color
$VTE_VERSION 3409
Have you found a fix?

@stanislas-brossette You can test #6997.

Disabling cursor shapes (see command in :help guicursor) helped to fix it on Guake (Ubuntu 17.04).
Thanks for the tip @justinmk :)

I've had this issue for a while since I didn't know how to google for this. Just tried :help guicursor disabling trick and it totally worked 🎉 Thanks for the tip!

Edit: This + combination of set -g terminal-overrides ',xterm-256color:Tc' from #5096 did the trick

I also had to set :set guicursor= in my .vimrc to avoid this problem, using Ubuntu 16.04.
