Public bug reported:
I believe this bug is related to the video driver but I'm not sure ...
Anyway there goes the report:
This is a crash that happens every time I open two different
applications (for example: Chromium and Nautilus), one of them in
workspace 1 and the other in workspace 2.
When I change the focus between them for some time (from 3 to 5 times),
there is a crash that causes, first, the window manager (or gnome shell,
I'm not sure) to reboot, then, if I insist on trying to switch between
the applications for some more times, the crash seems to be more severe
and ubuntu returns to the login screen (gdm3).
I'm using a dell inspiron 15 series 7000 (gaming), notebook with 2
displays (one is the display of the notebook itself and the other is an
LG 23EA53, connected via HDMI and configured as a primary)
To make the focus change I use the mouse, I click on "Activities" and,
with the mouse, I click on the application that appears in the
workspaces pile to the right of the display, below and above,
successively until the crach occurs.
Using Alt-TAB it seems at first that the crash does not occur ... or it
takes longer to occur :-)
This crash occurs when both applications are in the same workspace as
well ... And if one of the applications is a virtual machine session of
Virtualbox, crash occurs more quickly (with less focus shifts).
