I have only started recently using Joplin. Before, I used Samsung Notes and OneNote. Mostly I do use handwriting with S-Pen and my tablet (Galaxy Tab S6). I'm used to write almost as smooth as I do it on paper. However now with Joplin it only gives me a reasonable handwriting result when I write very slowly, else the handwriting looks scratchy and while writing it always exists a certain time lag. Are the any settings I probably need to adjust or is the handwriting quality simply not the same as I'm used to have with Samsung Notes?
Samsung Notes (I have 4 Samsung tablets) was specifically designed to match the hardware in a Samsung tablet. They probably spent a ton of money to develop that smooth writing. If the developers of Joplin had a ton of money and access to the Samsung proprietary design specs their pen use might be close to Samsung's. Donate a few hundred thousand bucks and convince Samsung to hand over their design secrets and the Joplin devs will get right to work on it.
Samsung uses Wacom technology for their pens and digitzers, which is basically the industry standard . I cannot speak for Samsung Notes specifically, but I use a Wacom pen to write using Xournal++ under Windows, and the experience is silky smooth there, so I'd say it should definitely be doable in other applications as well.
Enabling stabilization should reduce scratchiness, but will also increase latency.
Additional notes: Joplin's inking functionality currently runs in a WebView. This simplifies cross-platform development but introduces a few limitations. For example, the eraser button doesn't work on some tablets (see this Chromium bug report) and there may be higher latency.
To reduce latency, Joplin does try to use the web Ink API, when available. Unfortunately, this API seems to be unsupported or broken on Android (despite being listed as supported here).
I cannot judge whether it is a matter of lag of development resources - I'm not a developer. There are many features in Joplin much better like in Samsung notes, so apparently it is not always a matter of money. Many thanks for your input guys. The recommended settings indeed mitigate the issue slightly, however apparently it is not made to write longer text. Also when my hand is touching the panel during writing I always accidentally draw lines on the panel. Don't get me wrong - Joplin is an excellent tool and will use it anyway.
