Public bug reported:
I believe this is caused by the panel and dock transparency animations
on the Ubuntu session (not the vanilla Gnome session). This is best
replicated on a multi-monitor set up.
Scenario 1:
- Open some app, make full screen on monitor with panel and dock - panels are
now opaque
- Open some other app unmaximized
- Rapidly drag back and forth between monitors
- Everything's good
Scenario 2:
- Ensure no app is making the panel / dock opaque
- Open some app unmaximized
- Rapidly drag back and forth between monitors
- Crash
Now this happens both on X (where Gnome restarts) and Wayland (where we
get kicked out to the login screen). Just before the crash, CPU usage
spikes and frame rate drops dramatically.
Ubuntu 17.10, Wayland and X, intel graphics.
I can't find no gnome logs anywhere, but a 270MB binary file appears at
~/core, do you need this?
