Bug#1116034: Critical Bug Report: Segmentation Fault in libX11 with Huion Tablet on Debian 13 (Trixie)

Package: libx11
Dear Debian Bug Triage Team,
I am writing to report a serious bug where the libX11 library experiences a segmentation fault when a Huion tablet is connected, leading to system instability and rendering the device unusable.
Problem Description
When my Huion Inspiroy H1060P tablet is connected to a system running Debian 13 (Trixie), a .NET application (likely the official Huion driver) triggers a segmentation fault within the libX11.so.6.4.0 library. This issue does not occur on Debian 12 (Bookworm) with the same hardware and software, suggesting a regression in the version of libX11 shipped in Trixie. The kernel logs clearly indicate the segfault, and the system fails to correctly handle the tablet's input.
Reproduction Steps
Install a clean version of Debian 13 (trixie) with the X11 windowing system.
Install the proprietary Huion driver software.
Connect the Huion Inspiroy H1060P tablet (USB ID: 256c:006d).
The system logs will show a segmentation fault, and the tablet will not function.
System Information
This information was gathered from the terminal using standard commands.
