UHD630 Offscreen rendering

Jump to solution

Hello,

 

We used to render offscreen a 3D scene in WPF (render in a window not located in the screen) then copying it to a bitmap.

Everything works fine on i7 6700 (HD Graphics 530), i7 7700 (HD Graphics 630) but not on i7 8700 (UHD Graphics 630).

 

Has anything changed about offscreen rendering ?

Is there an option to enable/disable to make it works like before ?

 

Thanks in advance for your response.

After deeper researchs, it appears that the guilty is the 1809 update for Win10 that changed PrintWindow and not the chipset.

Hello Leo,

 

I can reproduce the issue on 3 differents computer of the same model : Dell Optiplex 7060 (i7 8700)

Before upgrading to Dell OptiPlex 7060, we had :

  • Dell OptiPlex 7050 (i7 7700)
  • Dell Precision 3620 (i7 6700)
  • Dell OptiPlex 9020 (i7 4770)
  • Dell OptiPlex 9010 (i7 3770)
  • Dell OptiPlex 980 (i5 660)

All of those systems worked, but not the 3 new computers 7060.

 

We are a software editor and we use WPF to render 3D models.

We have a window with WPF controls and copied with PrintWindow (User32.dll).

If the window is partially located out of screen, the bitmap result is up to date only for the in-screen region of the WPF window. If the window is totally out of screen , the obtained bitmap is empty (or the last correct render if the window was on the screen before)

 

This is explained by the attached images (next message since I can attach only one file per post).

 

You will find attached the log of SSU executed on a 7060 computer.

Hello CForg1 Please provide me with the detail step to replicate the behavior, and the download links of the software used in the behavior. Have you notify the application developer of the behavior? Hope this helps. Regards, Leonardo C. Intel Customer Support Technician Under Contract to Intel Corporation
