Bug: Navigating Lucid board with wacom tablet pen

Hi ​@per,

Thank you for posting in the Lucid Community!

I understand how this would disrupt your workflow. To take a closer look at the issue you’re experiencing, could you try the following workarounds?

• The most common cause is Windows Ink. While it’s meant to help with handwriting, it often forces the browser to treat every pen touch as a primary click/draw action, ignoring keyboard modifiers like the Spacebar.
  • Open your Wacom Tablet Properties, go to the Mapping tab, and uncheck “Use Windows Ink”.
  • Wacom has a specific walkthrough for this behavior here: Why is my pen not scrolling or panning correctly?

• If you are using a Chromium-based browser (Chrome, Edge, or Brave), the browser engine itself might be the bottleneck. These browsers are notoriously aggressive with pen input. Firefox uses a different engine (Gecko) to handle “Pointer Events.” Many users find that Firefox respects the Spacebar + Pen combo perfectly while Chrome fails.
• In your browser settings, search for “Hardware Acceleration” and toggle it to the opposite of its current setting. This changes how the browser communicates with your graphics card.

• It’s possible that WebGL is causing an issue with your graphics card.

  • Try turning WebGL off by going to View > Rendering > Use WebGL and unchecking the option.

  • For more information on WebGL, check out these resources:

• If the pen gets stuck in “draw mode,” try pressing “P” (Freehand Draw) and then “V” (Selection Tool). This manual toggle can force Lucid to re-sync the active tool with your pen's input.
• Some users report that switching the Selection Mode (in the primary toolbar) from “Box” to “Freehand” clears the conflict.

Please let me know if you are still running into issues after attempting the workarounds above. Thank you for your help and patience!
