So GNOME Terminal isn't the problem. > Probably the design of the program for the rare case of extremely long > lines requiring wrapping is causing the delay. I don't know what it is. These btrfs debug files don't have many lines longer than 60 characters. A scant handful might be up to 80. The only thing I see that makes lines long are long file names. -- Chris Murphy -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://lists.fedoraproject.org/admin/lists/users@lists.fedoraproject.org Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
