The issue persists in 22.04. Not sure if it should be fixed in upstream: https://gitlab.gnome.org/GNOME/gtksourceview/-/issues/121.
However at least gedit behavior in Ubuntu 22.04 is better than in 21.10 (maybe fixed in new Gnome Shell 42.0). Let's say you have a JSON file, not prettified, 1.9 MB size, whole content on one line. If you open the file in gedit, then: 21.10: gedit freezes (CPU 100% forever) and if you right click to app icon to dock, mouse and keyboard stops working and OS becomes unresponsive - you need to restart OS 22.04: gedit freezes (CPU 100% forever), but no OS freezing on right click in dock -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/505765 Title: gedit problem with long lines To manage notifications about this bug go to: https://bugs.launchpad.net/gedit/+bug/505765/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
