LightningChart Support Forums

Hi

I have a problem with the LightningChart Ultimate WPF/Winforms Demo (.net4) v6 and have the same problem with the chart in my application v5. When I lock and unlock windows 8, the chart disappears. In your demo in version 5 it works, in demo version 6 not. In my wpf chart wrapper with version 5 it disappeared also, but only when the application window is behind another window.
Is that a bug or have I forgotten something?

Regards,
Raphael

Hi Raphael,

Lock/unlock should work, we can't reproduce this.
Could you tell us which GPU you use?
You can find the GPU on a GPU information window in our demo applications.

Hi Tero

Here is the gpu info: I've made some test with other computers with windows 8, 8.1 and 7 and found a solution to reproduce the bug. We have all two displays. If the chart is on the primary display, the chart is visible after unlock. If the chart is on the second screen, the diagram is for a short time there and then disappears after unlock.

Hi Salto,

Thank you for more information.

We can now reproduce the problem and it will be fixed in the next release.

Sorry for inconvenience.

We made the 6.0.3 hotfix assemblies today, with this fix included. Download it from Customer area (link was provided with the license keys)
