Fixing Pen Cursor Freeze (Drag Threshold)

If your pen cursor stays frozen at the touch point when you start drawing and only begins to move after you drag it a noticeable distance, your tablet driver's drag threshold setting is likely too high. This article explains the problem and how to fix it.

Symptoms

  • The cursor does not move when you first touch the pen to the tablet surface. It “jumps” to the correct position only after you move the pen far enough.
  • You cannot draw small dots or short strokes — they simply don't appear.
  • The beginning of every stroke is missing a small segment.
  • This happens in all applications (not just T-Sketch), including other drawing programs and even the operating system itself.

Why This Happens

Most tablet drivers include a drag threshold (also called “double-click distance” or “click sensitivity”). This creates a dead zone around each pen-down point. The driver holds back cursor movement within that zone so it can tell the difference between a click and a drag.

This is useful for general desktop work — it prevents accidental drags when you tap to click. But for drawing, it means the operating system literally ignores your pen movement until you've traveled past the threshold distance. No application can override this because the events never reach the browser.

How to Fix It

Open your tablet driver's settings and reduce or disable the drag threshold. The exact steps depend on your tablet brand.

Wacom (macOS and Windows)

  1. Open Wacom Tablet Properties (or Wacom Center on newer drivers).
  2. Select your pen from the device list.
  3. Go to the Pen tab (or Tip section).
  4. Find Tip Double Click Distance and set it to Off or drag the slider all the way to the left.
  5. Click OK or Apply.

On older Wacom drivers, this setting may be labeled Double Click Distance or Click Threshold.

Huion (macOS and Windows)

  1. Open the HuionTablet application.
  2. Go to Pen settings.
  3. If you see a Mouse Mode vs Pen Mode toggle, make sure Pen Mode is selected. Mouse Mode adds extra cursor smoothing and thresholds.
  4. Reduce or disable Click Sensitivity if the option is available.

XP-Pen (macOS and Windows)

  1. Open the PenTablet application.
  2. Go to Pen settings.
  3. Reduce the drag threshold slider to the minimum value.

Apple Pencil (iPadOS)

Apple Pencil does not have a configurable drag threshold. If you experience a similar issue on iPad, make sure iPadOS is up to date. If the problem persists, try unpairing and re-pairing the pencil in Settings > Bluetooth.

Samsung S Pen (Android / ChromeOS)

Samsung S Pen typically does not have a drag threshold setting. If you experience similar behavior, check Settings > Advanced features > S Pen for any pointer-related options.

Windows Ink (Windows)

On Windows, some tablet drivers route pen input through Windows Ink. If your tablet driver's settings don't resolve the issue, try toggling the Use Windows Ink checkbox in the tablet driver's settings panel. Some applications work better with it enabled, others with it disabled.

How to Verify the Fix

  1. After changing the setting, open T-Sketch (or reload the page if it was already open).
  2. Select any drawing brush.
  3. Tap the canvas quickly without dragging — you should see a small dot appear immediately.
  4. Draw a tiny circle. The stroke should follow your pen from the very first moment it touches the surface, with no delay or jump.
