i am not asking for help. this is a bug report. i am reporting a bug.
if there is useful information i can gather i am happy to do so.
4) the steps in the description of this bug were performed in fairly
rapid succession, so several apps were busy starting up. The lockup
occurred instantly after maximizing the xterm. 6) killing Xorg freed
the terminal. 3) it is not consistently reproducible. Under xenial it
happens watching videos (Bug #1744429). Since installing bionic, videos
haven't tripped it so far. This bug report describes an occurrence that
didn't involve a video.
5) here is what htop looks like right after logging in, launching
startx, 2 xterms, and htop:

Title:
[Dell OptiPlex 755] xorg hangs
Status in xorg package in Ubuntu:
Incomplete
Bug description:
The problem is that my GUI stops responding after launching a few
applications, and is correlated to high CPU utilization of xorg.
An example reproduction scenario:
launched startx,
launched an xterm via twm,
launched another xterm via the first,
launched tmux,
launched firefox-esr, bluetooth-manager, and pavucontrol,
maximized the xterm running tmux
xorg stopped responding, ctl-alt-Fn don't respond either
logged in via ssh, attached to tmux, launched htop, copied htop
output, in which you can see xorg consuming lots of cpu.
