I just got a brand new huion kamvas pro 19 and a new computer with 32gb ram, it is impossible to work when this keeps happening, doesnt happen with mouse, only on pen. all drivers on PC and versions on adobe and huion are on par
We understand that encountering technical issues can be frustrating. Would you mind disabling Windows Ink under the Wacom tablet settings and then relaunching Illustrator to check if it helps?
Also, try running Illustrator under Safe Mode (Windows / macOS) and share your observations.
