It happens only on some of our client's computers even for the simplest demo. I can't repeat it in development  environment.

The OS is Windows 7 x64, .net framework version is 4.7.2.

The operation triggers the error is just dropping down and select items. 

I think the problem happens when rendering the selectionbox.
