Public bug reported:
Behaviour: Sometimes gnome-terminal does not repaint the screen
correctly after the text has changed.
This happens in only a few specific cases that I have encountered, yet
happens fairly reliably in those cases. I have not been able to track
down exactly what situations in general reveal this bug, but I have been
able to reproduce it reliably with the following steps:
1) Create a gnome-terminal window which is 80x24. Other sizes may work
as well, but it is important that the number of rows is fewer than the
number of lines in the attached test script.
2) Run the attached test script in the terminal.
What should happen: The screen should be reset, then the program should
be output, then after a 1 second delay, the screen should be reset and
the program should be output.
What happens: The second time the program is printed out, the screen is
not painted correctly.
I am running 12.04.1 Precise, x86-64. I first encountered this problem
at least two versions ago. I have encountered it on two different
computers, both using the proprietary nvidia driver.
The bug occurs whether or not a compositor is used, and whether or not
transparency is turned on in gnome-terminal. Based on this, I doubt that
the problem is the nvidia driver.
