I am sorry to hear about the encountered issue with Step Builder and will try to help you resolve it.
Based on the provided information, I believe this issue is caused by the rendering optimization in Visual Studio 19's latest releases and it is common for a number of extensions like ours. To fix it, please follow the steps below to disable the rending optimization option in Visual Studio 2019 on your machine.
- Open Visual Studio 2019 and your project and enable the Step Builder (if it is not enabled already). - Go to Tools -> Options and disable the option "Optimize rendering for screens with different pixel densities" in the General tab (see optimizeRenderingVS19.png). - The above change requires you to restart Visual Studio, so do that and reopen the project.
I hope the above suggestion will help resolve the issue and you can continue using the Test Studio extensions in Visual Studio without any troubles. Please do not hesitate to contact us again, if you need further assistance.
