Unfortunately, now that I try it, it's broken for me.  And it's broken in a very bad way -- I think
this should block the release or be disabled until we figure out what's wrong.  It definitely
makes GDB unusable for me.

The trouble is that now pressing anywhere on the screen with the mouse just results in
weird characters being printed on the command line window (probably uninterpreted control
sequences).  That even prevents me from selecting text (something I do often) -- I wanted to do
that to paste the results here.  I even tried suspending GDB with ^Z to then copy the text, but
that still leaves the mouse messed up.  See this screenshot:

This was on Ubuntu 20.04.
