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...
