May be a typo ?, here you can use sysinternal's notmyfault to test this bug. 1. launch qemu use legacy bios mode. make sure qxl driver is active, then open notmyfault64.exe click on crash button. It will trigger a bsod 2. without reset/patch, we cannot see bluescreen shown before qxl revision 5, even DodResetDevice does nothing, the qemu will do reset after detect qxl mode mismatch. see https://github.com/qemu/qemu/blob/ed71c09ffd6fbd01c2a487d47291ae57b08671ea/hw/display/qxl.c#L1315 But qxl revison 5+ requires explicit reset reference: not myfault: https://learn.microsoft.com/en-us/sysinternals/downloads/notmyfault DXGKDDI_RESET_DEVICE : https://learn.microsoft.com/en-us/windows-hardware/drivers/ddi/dispmprt/nc-dispmprt-dxgkddi_reset_device#remarks
