[DX] Texture appears scaled in MonoGameControl, but not in MonoGame project

[energyuser]

So I have a texture which I'm drawing in a MonoGameControl. The texture is 48x48 pixels, but when I open the form it is drawn in a 59x59 size, and is noticeably blurry. You can download and zoom these images for reference:

Normal Scaled

This happens with any texture I draw. I have a MonoGame (latest develop branch) project. I draw the same texture and it is drawn correctly.

What I've tried:

-Setting Editor.graphics's backbuffer width and height to the size of the control on the form -Setting the zoom of Camera to 1.0f -Form.AutoScaleMode =AutoScaleMode. None; -Form.DoubleBuffered = false;

My Environment: C# 7.3 Visual Studio 2019 .NET Framework 4.8

Try setting the AutoScaleMode of the Form like this:

AutoScaleMode = System.Windows.Forms.AutoScaleMode.None;

This is also possible from within the PropertyGrid via the designer.

Did you read my entire issue description? In it there's things I've tried, and setting AutoScaleMode is one of those things. It didn't work.

Maybe you need to use a manifest file and tell windows that your application is DPI aware.

Put the following file with the name app.manifest in your app root and select this file in the properties of your project as the manifest file.

<?xml version="1.0" encoding="utf-8"?>
<assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1">
  <assemblyIdentity version="1.0.0.0" name="Game4"/>

      <requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
        <requestedExecutionLevel  level="asInvoker" uiAccess="false" />
      </requestedPrivileges>
    </security>
  </trustInfo>

@sqrMin1 Sorry for the late reply.

Yes! Adding that manifest really fixed it. If I remove the manifest, a 100x100 texture will be drawn as a 125x125 texture (1.25 scale). In fact the whole window would be scaled, not just the texture.

Is there any way to fix that from within the library? If not, you should add it as a warning in the README.md for future users...

Thanks again.

This is not comming from the library. This is the regular Windows DPI scaling system.

In this case adding a manifest file to the project is the right solution and you should go with that.

Good idea. I added the specific information in the "Tips&Tricks-section" of the readme.md file.

Thank you for your suggestion and i'm glad I could help you with your problem.

Have a nice day!
