Windows 10 + older Intel HD integrated graphics card (HD2000, HD3000)

The editor runs on java, using jogamp for OpenGL support. Since Java 8u60, java.exe is marked Windows 10 Compliant by a small change in its embedded manifest. The Intel Windows 10 drivers only work on applications not marked Windows 10 Compliant. Go figure.

The editor appears to run fine if you undo the manifest change on the bundled java.exe. You can get a patched version here: java.exe You can do it yourself by following these instructions:

First you need the Manifest Tool. It's distributed as part of the Windows SDK. You probably already have it if you have Visual Studio installed.

1. Make sure you have mt.exe installed

C:\Users\your.name>mt.exe

2. Move into the jre\bin subdirectory of your Defold installation

C:\Users\your.name>cd Defold\packages\jre\bin

3. Extract the manifest from java.exe

C:\Users\your.name\Defold\packages\jre\bin>mt -inputresource:java.exe -out:java.manifest

4. Open the java.manifest you extracted above in your favourite editor

C:\Users\your.name\Defold\packages\jre\bin>notepad java.manifest

5. Locate the compatibility section:

<compatibility xmlns="urn:schemas-microsoft-com:compatibility.v1">
  <application>
    <supportedOS Id="{e2011457-1546-43c5-a5fe-008deee3d3f0}"></supportedOS>
    <supportedOS Id="{35138b9a-5d96-4fbd-8e2d-a2440225f93a}"></supportedOS>
    <supportedOS Id="{4a2f28e3-53b9-4441-ba9c-d69d4a4a6e38}"></supportedOS>
    <supportedOS Id="{1f676c76-80e1-4239-95bb-83d0f6d0da78}"></supportedOS>
    <supportedOS Id="{8e0f7a12-bfb3-4fe8-b9a5-48fd50a15a9a}"></supportedOS>
  </application>
</compatibility>

6. The last line <supportedOS Id="{8e0f7a12-bfb3-4fe8-b9a5-48fd50a15a9a}"></supportedOS> is what marks java.exe Windows 10 Compliant. Remove it or comment it out. Save.
7. Embed the manifest again

C:\Users\your.name\Defold\packages\jre\bin>mt -manifest java.manifest -outputresource:java.exe;#1

8. Start the editor
