System.Windows.Media.Imaging.RenderTargetBitmap.Render does not render from remote desktop #3765

Open vsfeedback opened 3 years ago

vsfeedback commented 3 years ago

This issue has been moved from a ticket on Developer Community.

I am not sure but I think the System.Windows.Media.Imaging.RenderTargetBitmap.Render method does not render content of System.Windows.Media.DrawingVisual object on System.Windows.Media.Imaging.RenderTargetBitmap if application is running thru a remote desktop session and the user disconnects from the remote desktop while application is running.

The problem can be reproduced using the following steps:

1. Project file attached rdptestwpf-1.zip

2. Open project in Visual Studio 2019 in local computer with Windows 10.

3. Compile project.

4. Connect to the local computer via remote session.

5. Start project in Visual Studio.

6. Wait while progress will going and close the remote session.

7. Login to the local session and see image files in project's output path. The "first" group of images will contain white rectangle with green line.

The "second" group of images will contain black rectangle (empty content). The "second" group of images was created when user closed the remote session.

I have detected that for the last 35 days, this issue didn't have much product team activity and a very small amount of new votes or comments. Based on this, its severity, and affected area, it’s my experience that this issue is very unlikely to be fixed.

Hi, In Windows server datacenter 2019 version 17763.2114 there is no problem. In Windows server datacenter 2022 version 20348.405 we got this problem.

When we connected to the user on the remote desktop everything is ok and WPF will render the views. but when we disconnect from remote desktop, WPF cannot render the bitmap.
