Render Close -- Black Screen Hang

If I close the render window it turns black and the main blender window freezes requiring a restart to recover. Didn’t find this issue in search. Maybe I am not using the correct search terms.

Comments please.

Could you try a few of these and report back.

Minimize (Esc) the render window and rightclick to close it from the taskbar.
In F10, Output tab, change from “Render Window” to Fullscreen and Image Editor and close them with Esc.
In Control Panel >> Display Properties, turn down Hardware Acelleration and test all three windows again.

Same behavior as closing the window with the mouse.
Except there is a different behavior from most windows; with right click of the taskbar the render window maximizes.

In F10, Output tab, change from “Render Window” to Fullscreen and Image Editor and close them with Esc.

Works with no error.

In Control Panel >> Display Properties, turn down Hardware Acelleration and test all three windows again.

Could find a specific turn down for hardware acceleration.
Enable applications settings override is checked and the sharpness slider is already at minimum.
