Blanking remote with Intel Graphic HD = hang

Hi, after a few test there seem to be a bug with the remote management and when we blank the screen, or if we use the remote diagnostic (which blank the screen) with the latest Intel Graphics HD that come with the Dell Optiplex 7010.
The remote become unusable, one click take about 1 minute to do!!

I tested the same workstation with an addon graphics display (AMD Radeon) and the remote is ok.

The workstations are Windows XP, and we have ZCM 11.2.3a on both servers and workstations.

Does someone saw this bug?

thanks
Eric.
