What os are you using? I found it extremely glitchy on windows, but pretty good on Linux. (It still crashes sometimes when I leave it open for a long time on Linux, but still the best handwriting app I've used on windows or Linux.)

Linux (KDE Wayland/GNOME Wayland, Gnome was a bit better for touch use in general but the glitches were the same, IIRC) on a tablet with a Wacom digitizer.

The problem sadly is Wayland. While wayland generally improves touch input, Xournalpp has those hiccups & glitches, for the ones are know are actually GTK bugs. I'm still sticking with Wayland though. I used Xournalpp one year before I switched on Xorg.
