Title:
[Dell OptiPlex 755] Intermittently GUI hangs with high xorg CPU% after
launching applications
Status in xorg package in Ubuntu:
New
Bug description:
The problem is that after launching a few applications, the GUI may
become unresponsive, although this is not consistently reproducible.
When the GUI is unresponsive, it is correlated to high CPU utilization
of xorg.
An example reproduction scenario is launch the following in order, and
quickly:
startx
xterm via twm
another xterm via the first xterm
tmux
firefox-esr
bluetooth-manager
pavucontrol
While the above are launching, maximize the xterm running tmux, and
the GUI immediately becomes unresponsive. For example, Ctrl+Alt+Fn
don't respond.
After this, I logged in via ssh, attached to tmux, launched htop,
copied htop output, which shows xorg at 94.6 CPU%.
