Title:
Gnome-shell acting very poorly under stress
Status in gnome-shell package in Ubuntu:
Expired
Bug description:
How to reproduce:
* in Gnome-shell, starts VLC. Drag and drop a .str file into VLC (without
providing it any video file).
* A bug in VLC will make it use 100% CPU for quite a long time.
* Meanwhile, in a terminal, type “top”.
* Gnome-shell will appear as one of the programs taking a lot of resources.
* Shortly after, the whole Gnome-shell will freeze and no longer respond.
This is a stressful situation for the user: not only is the computer burning
hot, but the window manager is no longer responding.
* Ctrl+Alt+F3 to open a TTY, kill -9 <pid of gnome-shell>
* Gnome-shell restarts, enabling you to interact with the windows, but
shortly afterwards, everything will freeze again.
In this situation, the system is under huge stress because of VLC.
However, this should not be an excuse to let the whole system stop
responding altogether. There is clearly an issue in VLC here, but
this kind of gnome-shell freeze appears with a variety of system-
stresses on my computer, not just VLC. It may be that VLC is causing
a lot of system calls that are caught by Gnome-shell? I am not sure
what exactly is happening.
I am not sure even whether this is really an issue with Gnome-shell:
it may be an issue with its parent process, or whatever.
System stress is not an ideal situation, and I fully understand that
it can be difficult to deal with. I just feel that Gnome-shell could
handle it slightly better.
I would understand that this bug report might be too subjective and be
marked as invalid. Anyway, I just wanted to share my frustration. If
I can help in any way, please tell me how ☺
