Title:
gnome-shell assert failure: double free or corruption (fasttop) in
g_free() from g_error_free() from cogl_error_free() from
cogl_texture_new_with_size() from
clutter_offscreen_effect_real_create_texture()
Status in mutter package in Ubuntu:
Fix Released
Bug description:
[ Impact ]
Gnome shell crashes on double free
Problem is occurring if dual monitor is used. Second monitor is
repeatingly blank and activated again. At the bottom it probably
contains the upper part of the first monitor. I had the same problem
at 18.04 when using gdm3 without wayland during logon.
[ Test case ]
- Run gnome-shell with multimonitor
- No flashing should happen on gdm initialization
Also we should monitor crashes in e.u.c
[ Regression potential ]
Low, the proposed fix is part of the current stable branch upstream
and not changed in further revisions.
