Yes it's possible one of your icons uses 16-bit colour, and explains why we don't see other/many reports of this crash.
In theory we should hit this problem more often, given that we have: /usr/share/icons/hicolor/ and "high color" means 16-bit (or 15-bit). But apparently most icons in there are "true colour" instead. ** Also affects: mutter (Fedora) via https://bugzilla.redhat.com/show_bug.cgi?id=1239129 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1766938 Title: gnome-shell crashed in standard_pict_format_for_depth() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1766938/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
