Question details

The user needs to fix an issue where an XP-Pen tablet draws random vertical lines on slides while recording a PowerPoint presentation using Kaltura.

How to Fix XP-Pen Drawing Random Vertical Lines in PowerPoint

Product: Microsoft PowerPoint, Kaltura, XP-Pen
Device & OS: not provided
Scenario: Recording a slide presentation with Kaltura while using an XP-Pen tablet to annotate the slides.
Observed behavior: Unwanted, random vertical lines appear on the PowerPoint slides when trying to draw with the tablet during an active screen recording.

Before you start

Ensure your XP-Pen tablet is securely connected to your computer and save any open PowerPoint presentations before beginning the troubleshooting process.

Solution 1Recommended

Isolate the Software Conflict

Determine whether the issue is caused by PowerPoint itself or by a conflict with the Kaltura screen recording software.

Since multiple software applications are running simultaneously, isolating the apps will help identify the root cause of the ink glitch.

Close Kaltura completely

Exit the Kaltura recording software entirely. Ensure it is not running in the background by checking your system tray or task manager.

Test PowerPoint independently

Open Microsoft PowerPoint, start a slideshow, and use your XP-Pen to draw on the slides. Observe if any random vertical lines appear.

Evaluate the results

If PowerPoint works normally and the ink is smooth without Kaltura running, the issue is a software conflict between Kaltura and the XP-Pen driver.

Testing on Another Device: If possible, install Kaltura and the XP-Pen driver on a different computer and test PowerPoint to see if the issue is specific to your current operating system environment.

Solution 2

Update or Reinstall XP-Pen Drivers

Outdated or corrupted tablet drivers can cause input tracking errors, resulting in straight, random lines.

Solution 3

Contact Technical Support

If software isolation and driver updates fail to resolve the problem, escalate the issue to the respective product support teams.

Frequently Asked Questions

Why does my drawing tablet glitch when I record my screen?

Screen recording software captures system resources and display data simultaneously. If your computer's CPU is overloaded or if there is a conflict between the tablet driver and the recording software, the system may drop input tracking points. This causes the tablet to draw straight, random lines instead of smooth curves.

How can I tell if the issue is with my tablet or the software?

You can isolate the issue by closing the screen recording software completely and testing the tablet in a standard drawing app or a blank PowerPoint slide. If the tablet draws normally without the recorder running, the hardware is fine, and the issue lies in a software conflict.

Does WPS Office support drawing with an XP-Pen tablet?

Yes, WPS Presentation fully supports standard digital ink inputs from graphic tablets, including XP-Pen. You can use your stylus to draw, highlight, and annotate slides directly within the software.
