EF Team Triage: This issue is lacking enough information for us to be able to effectively triage it. In particular, it is missing the following information requested in the new issue template. Can you please provide this information?

Steps to reproduce

Ideally include a complete code listing that we can run to reproduce the issue.
Alternatively, you can provide a project/solution that we can run.

BTW we're not just doing this to be mean 😄... we get a lot traffic on this project and it takes time to attempt to reproduce an issue based on fragments of information. In addition, our attempt is often unsuccessful as the exact conditions required to hit the issue are often not explicitly included in the code provided. To ensure we maximize the time we have to work on fixing bugs, implementing new features, etc. we ask that folks give us a self-contained way to reproduce an issue.

For a guide on submitting good bug reports, read Painless Bug Tracking.

BTW this is a canned response and may have info or details that do not directly apply to this particular issue. While we'd like to spend the time to uniquely address every incoming issue, we get a lot traffic on the EF projects and that is not practical. To ensure we maximize the time we have to work on fixing bugs, implementing new features, etc. we use canned responses for common triage decisions.

Same here. 16.1, ef model, model browser empty or containing data from previously active tab. Steps to reproduce - open edmx designer with old edmx file and then model browser.

I'm using Visual Studio 2019 version 16.1.1 and EF version 6.2.
In order to reproduce this issue, I created a model based on an existing database, the application is built it's running with no errors.
But the Entity Data Model Browser Window is empty or gets "parts" from other opened windows (see bellow).

Same issue here. This is a brand new laptop, so it has only ever had VS 2019 Community installed, no prior versions. The solution was created in VS 2017. The Model Browser panel renders fine for the same solution on my other systems in VS 2019, though those machines also have VS 2017 installed, in case that helps any.

It's difficult to identify exactly what is wrong. The steps to reproduce are simple, open any EDMX and try to view the Model Browser. It's not rendering/painting anything; clicking in the unrendered area has no reaction.

Existing solutions exhibit the issue and I even created a brand new solution with a new EDMX, always the same result on this system.

I've repaired, and uninstalled/reinstalled EF6 Tools, all with no success. For now, I simply have to use another machine if I need to access the Model Browser, check in and pull on my new system. Everything functions fine, just cannot view the Model Browser at all. EDMX designer shows fine, shows tables, but right-click a table and click Show in Model Browser just shows an empty panel, or one with visual artifacts from whatever was displayed in that area previously.

Issue with the Entity Framework tools not rendering the model browser or table mapping view properly. All views open in VS 17, but not VS 19. They either open as a blank window or when docked on the side bar open with the previous views contents showing instead. For instance, right clicking an entity in the designer and choosing Model Browser would show the Model Browser tab selected on the right beside the Solution Explorer, but it would continue showing the contents of the Solution Explorer in the Model Browser tab.

Running
Windows 10 version 1809
Visual Studio Enterprise 2019 Version 16.1
.NET Framework 4.8.03761 (Note: 4.8 released Apr 18, 4 days before the issue was opened)

Uninstalling .NET 4.8. resolved the issue in Visual Studio 2019.

Unchecking in Tools -> Options -> Environment -> General -> Optimize rendering for screens with different pixel densities solves the problem with the rendering of the model browser and the table mapping views.
I also updated Windows 10 to the latest version (10.0.18362.145).

Thank you @melcug for the workaround. I just updated Windows 10 and unchecked Tools -> Options -> Environment -> General -> Optimize rendering for screens with different pixel densities. It worked like a charm.
