Describe the Bug

If you start a fullscreen game, and by some odds, Windows turns the monitors off due to inactivity, the entire system will hang. I left Sunshine on last night for my partner to play a game remotely through my PC, and when I woke up this morning my system was completely unresponsive (keyboard was stuck, couldn't toggle capslock, nothing worked) and had to manually power off and reboot. Upon reboot system was fine.

It would seem that if a game is in fullscreen, being streamed and Windows places the monitors in standby the system freaks out, and hangs.

Expected Behavior

When Windows initiates monitor power-saving mode (standby) while a game is running in fullscreen and being remotely streamed via Sunshine, the system should either:

• Suppreess the sleep timer due to active user input/video streaming activity, keeping the monitors awake.

• Gracefully handle the display state change by allowing the game and Sunshine encoder to continue running headlessly, or cleanly pausing the stream, without causing a kernel-level driver crash or hard system freeze.

Additional Context

• My setup is using dual DisplayPort Monitors
• I was streaming a fullscreen DX11 game at the time before falling asleep with my PC still on
• It's a complete low-level system hang, nothing responds, requiring a hard reset
• Using a virtual display driver might be able to help correct this
