I am writing to report a specific technical issue I encountered with my XPPen graphic tablet driver on macOS.

The Problem: After installing the latest XPPen driver and granting the necessary system permissions (Accessibility and Input Monitoring), the Globe/Fn key on my MacBook stops functioning as a language switcher.

Observation:

• When I press the Globe key, input source does not change.
• When I completely uninstall the XPPen driver and restart my Mac, the Globe key works perfectly again.
• If I reinstall the driver, the issue returns immediately.

This suggests a conflict between the XPPen driver's input handling and the macOS keyboard shortcut system. Currently, I am forced to use "Control + Space" to switch languages, which is inconvenient for my workflow as a teacher.

Device Details:

• Tablet Model: Deco 01 V3
• macOS Version: 26.4.1
• Driver Version: XPPenMac_4.0.14_260313

I hope your technical team can investigate this conflict and provide a fix in the next driver update.

Best regards
