Rpi4. turning on hw acceleration stop motion detection

Hi. After many tests a reddit post point me in the right direction fot that issue that drove me crazy for days. Raspbian installation only with shinobi additionally installed. All upgraded to the latest avaialble update at 13th june. With RPI hw acceleration enabled in monitor settings, there's no way to get motion detection working. Absolutely no detection with no redbar movements under the single monitor. Don't mind what you change in settings.

Disabling hw acceleration automagically do the works. Motion detection start to work again.

Obviously over limited platform like rpi, the hw acceleration is mandatory.. without it the board can't handle all the streams without smearing, smudging, loosing connections.

In monitor logs I do not notice nothing different between accelerated or not monitors.
