gnome-terminal doesn't redraw if content in a screen window changens

[Bård Aase]

gnome-terminal doesn't redraw if content in a screen window changens.

The problem seems to only occur when the window size is diffent than 80x24. And ONLY in Unity 3d. The problem doesn not occur in Unity 2d

This is what I do to produce the problem:

From a clean Ubuntu 12.04 32bit install
* Open Gnome-terminal. Resize the window.
* ssh somewhere
* attach to a running screen session with irssi
* type a message, and hit return.

Notice that the message does not appear until you hit ctrl+l or someone else says something in the channel.

-- OR --

From a clean Ubuntu 12.04 32bit install
* Open Gnome-terminal. Resize the window.
* run `man <something>`, for instance `man screen` or `man ls`
Do this several times... (a lot of times)
at some occasions, the man-page will fail to render, and you'll get a blank screen. If you move the cursor, the text will appear again.

I should also mention that the server I was ssh'ing into is running Ubuntu 10.04.4, with
Screen version 4.00.03jw4 (FAU) 2-May-06
and
irssi 0.8.14 (20090728 1938)

I also notice this problem outside screen, for instance when using ctrl+u to clear a line.

A temporary workaround for me seems to be to restart compiz after logging in.

[Bård Aase (elzapp)]

The problem, though visible in gnome-terminal seems to be closer connected to compiz

Status changed to 'Confirmed' because the bug affects multiple users.

"compiz --replace" doesn't recover from this issue.
After some time it is also seen with gedit and other apps. And after even more time key presses don't make text visible.

[Andrey Sidorov (andrey-desman)]

Reproduced with Unity 2D as well, so it's not compiz.

Can't ssh -X from 12.04 Unity 2D 32-Bit to a 64-Bit 11.10 pc.

Not reproducible after upgrade to Unity 5.12.0
