I'm not sure what you mean by "which software is creating the issue"--- the crashing process is gnome-control-center; everything else on the system is stable. I agree that it's not completely surprising that a request for a 242x43972 pixbuf might fail; it is surprising to me that the Control Center would request a 242x43972 pixbuf in the first place (screen hardware resolution and virtual desktop are both 1920x1080), and it's disappointing that the application doesn't deal more gracefully with a failed pixbuf allocation for whatever reason. i.e. I suspect that there are two separate bugs here, the failure to check the return value from gdk_pixbuf_new() (or related helper function), and the computation of the required pixbuf size in the first place. The request is probably for the application icon ribbon, but a height of 43972 would be enough to stack 458 96-pixel icons--- surely not all of those need to be in the display surface at one time. I will open an upstream ticket; started here because I used the Ubuntu crash reporter and it looked like it might be a library incompatibility issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938494 Title: Control Center crashes with SIGTRAP (from X11 MIT-SHM BadAlloc) on Applications view To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1938494/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thank you for the report but it would be easier to debug knowing which software is creating the issue. Could also maybe report it directly upstream on https://gitlab.gnome.org/GNOME/gnome-control-center/-/issues ? ** Changed in: gnome-control-center (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938494 Title: Control Center crashes with SIGTRAP (from X11 MIT-SHM BadAlloc) on Applications view To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1938494/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Looks like it's trying to create a window that's 242x43972 pixels so unsurprising that might fail. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938494 Title: Control Center crashes with SIGTRAP (from X11 MIT-SHM BadAlloc) on Applications view To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1938494/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
