• I confirm that this is an issue rather than a question.

Bug report

When Hyperion is set to capture screen with QT setting, mouse cursor blinks / flickers.
Changing capture frequency or picture decimation does not resolve.
Enable or disable Windows transparency doesn't resolve.
Changing some nVidia settings has no effect.

Steps to reproduce

Go to capturing hardware, enable screen capture, set device discovered to QT.
