Title:
Does not display VT-100 control codes correctly/consistently
Status in gnome-terminal package in Ubuntu:
Fix Released
Bug description:
I'm writing a shell script that draws in color to any VT-100 terminal.
The terminal in Ubuntu consistently and randomly drops out of graphics
mode producing huge glitches. This does not occur in Xterm or Gnome
Terminal on CentOS.
Appearance:
The image from the file below should look like a color filled square, what
you see is a "glitch" which looks like the second half of an escape command
followed by a lot of "a"'s where the graphical checkerboard character should be
rendered (in Ubuntu Gnome terminal it is rendered as a cursor that is the color
of a 50% blend between the background and foreground color, making it the best
appearing terminal I've used)
Reproducibility:
It is 100% reproducible with the instructions below.
To reproduce:
Using the attached screen-capture.txt file:
In Gnome-Terminal try "cat screen-capture.txt" over and over to see
the error.
In Gnome-Terminal try "less -r screen-capture.txt" and scale the
terminal window to see variation
Comments:
I don't know if there is a problem where characters are dropped from
stdin, or if the pipe is getting reset, or if the emulator can't keep up with
the commands, or if there is a(n inconsisent) limit to the number of command
codes that can be sent to the terminal. Or if it is being interrupted, or if it
randomly resets...
