THanks for the feedback.
Upon further checking of the logs, based on your dxdiag your graphics card name is Intel(R) HD Graphics 3000 but below the driver name shows “aticfx64.dll,aticfx64.dll,aticfx64.dll,amdxc64.dll” which is for AMD graphics driver.
Please double check on your side what exactly is your graphics adapter, is it really Intel or AMD?
This probably confuses spacedesk driver during grabbing and rendering the screen update.
Another possible reason is that your graphics adapter is already an old one which only supports WDDM 1.2. spacedesk IddCx Driver only supports WDDM 2.0 – above.
