Hardware acceleration set to max causes diagram drawing problems

[Richard Deverson]

Hello,
Hardware:
Dell Laptop with a NVidia display card
OS:
Win XP professional

The problem:
When hardware acceleration is set to max (via Display Settings), the diagram fails to display. The diagram is either shown with a grey background, or the underlying window is visible.

When hardware acceleration is set to medium, the diagram displays OK.

Has anybody had this problem?

Hi Richard,

I just tested on both a Dell Laptop with the NVidia display card, and an IBM laptop and did not encounter any problems with changing the hardware acceleration. Is this behavior specific to Essential Diagram, or are you noticing it for other .NET controls as well? Does this happen with the Essential Diagram samples?

Thanks,

Hi Prakash,
I''ve just done some more testing on my colleague''s laptop.

Yes, the behaviour is specific to Essential Diagram. We are using other .NET components and they seem to work OK.

We tested the Diagram Builder sample, and this seems to work OK.

Regards
Richard
