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).
