What happened?

Windows 11 immediately crashes in VirtualBox if "3D acceleration" is enabled.

"The workaround that has worked for me was to set the vRAM on the guest to 4096MB. I got the crash on 6144MB and 8192MB but again worked on 16384MB."

I can replicate and confirm this too. 4096MB or 16384MB fix the issue. Please fix 3d support on Windows guest with any VRAM size.

Thanks

How can we reproduce this?

Set a Windows guest with this vRAM size --> 8192MB or 6144MB.

Star using Windows, and soon the virtual machine crash, for exmple with enter in Full Screen Mode.

4096MB or 16384MB in vRAM fix the issue!
