I am pretty sure the problem lies in Gnome Canvas. It allocates a gdk graphics context for every stroke, even when they are not visible. The attached patch to libgnomecanvas alleviates this problem: xournal will still be (very) slow in continuous page mode, but not in single-page mode.
I am not saying this is a good patch; it may break other programs depending on libgnomecanvas. You should regard this as a proof that the problem is actually where I'm saying. Please test & confirm. ** Package changed: xournal (Ubuntu) => libgnomecanvas (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/657783 Title: xorg 100% cpu while using xournal -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
