Brush strokes cut off after 3 seconds — affects both tablet and mouse (v29.8.3–30.0)

[HamburgerC]

I’m experiencing a frustrating issue in Illustrator where my strokes are cut off after about 2–3 seconds of continuous drawing. This happens whether I'm using my XP-Pen Artist 22R Pro or just a regular mouse — so it doesn't seem related to pen pressure or tablet input alone.

Versions tested:

Illustrator 30.0

Illustrator 29.8.3

Illustrator 29.7.1

All show the same issue across both my main PC and tablet monitor.

What I've already tried:

Disabled and enabled Windows Ink in XP-Pen settings

Reset Illustrator preferences

Reinstalled Illustrator and XP-Pen drivers (clean install)

Confirmed the issue occurs even with just a mouse

It seems like Illustrator is stopping input after a few seconds regardless of device. Has anyone else seen this? Any known fix or setting I’ve missed?

I've seen something similar in many different Illustrator versions, but not in terms of a time frame. Rather dependent on the length of the path one is drawing continuously. At some undefined point the tool (e.g. Brush tool, Pencil tool) stops drawing the path you are drawing abruptly.

Some other tools like the Knife tool seem to be affected as well by this issue.

Currently I do not know a workaround to prevent it.
