Comment 8 for bug 1634451

It was not quite correct what I said about flickering stopping only when mouse moves. It also stops when something is output continuously to the terminal window. For example, running the following command in gnome-terminal window:

perl -MTime::HiRes -E '$i=0;while (1) { $i++; Time::HiRes::sleep( 0.2 ); say "Hello $i" }'

causes the flickering to stop. However, if I increase the sleep delay between writes to the terminal from 0.2 to 0.3 seconds, flickering starts again. So the output must be continuous for the flickering to stop.
