WPF (Windows Presentation Foundation) Touchscreen Crash - Visual Studio

[davedebris]

Hello!

We are currently using a DisplayLink Driven Touchscreen LCD (specifically MIMO UM-1070) and have been experiencing crashes whenever the touchscreen is touched.

Research I've done online leads us to to the fix proposed by MSDN here: https://msdn.microsoft.com/en-us/lib...(v=vs.90).aspx

The above fix would require a software change for us which is currently not ideal.
Does anyone have any expertise on this or any ideas how to fix this problem without addition of the code? Maybe a driver update? Beta driver?
Any advice?

Thanks in advance!

Here is an Event Viewer Windows Application Log of the crash:

p.s. I did a search on the forums and didn't find anything WPF

Did you found solutions?
I have exactly the same problem.

WPF application crashes on DisplayLink managed screen.
In Windows Surface Simulator everything works perfect.

Disable native touch support. And all controls can't have native scroll.
