What happened?

When opening the Kitty terminal emulator inside a Linux guest with VMSVGA graphics controller and 3D Acceleration enabled, VirtualBoxVM.exe crashes immediately with an application error:

"The instruction at 0x00007FF841282D80 referenced memory at 0x0000000000000008. The memory could not be read."

The VM becomes completely unresponsive and must be deleted and recreated. The crash is 100% reproducible every time Kitty is launched. The issue occurs regardless of host hardware (tested on AMD Ryzen 7 8845HS, AMD Ryzen 7 6800H, Intel N150, Intel Core i7).

The crash appears in VBox.log as:

!!! rtR3WinUnhandledXcptFilter caught an exception
ExceptionCode=0xc0000005
ExceptionAddress=00007ff841282d80
ExceptionInformation[1]=0000000000000008

Guest reports OpenGL 4.1 via Mesa 26.0.6 / vmwgfx 2.21.0.0 before the crash.

How can we reproduce this?

1. Create a Linux VM with VMSVGA, 256MB video memory, 3D Acceleration enabled
2. Install a Debian Testing based Linux distribution with kernel 7.0.x and Mesa 26.x
3. Install VirtualBox Guest Additions 7.2.8
4. Boot the VM and open Kitty terminal
5. VirtualBoxVM.exe crashes immediately

Note: without 3D Acceleration, Kitty opens and works normally. The crash only occurs when 3D Acceleration is enabled and Kitty attempts to initialize an OpenGL context.
