Eirik Bakke commented on NETBEANS-1227:
---------------------------------------
The manifest in Java 11 is updated to mark Java as having "PerMonitorV2"
support. See https://bugs.openjdk.java.net/browse/JDK-8199627 . The NetBeans
IDE and Platform launchers should do the same. It wouldn't hurt to include the
"compatibility" section of the manifest as well, to tell Windows explicitly
that Java (and by extension, NetBeans) supports Windows 8.1, Windows 10 etc.
Here are the relevant sections from javaw.exe in JDK 11ea:
{code:xml}
<asmv3:application>
<asmv3:windowsSettings
xmlns:dpi1="http://schemas.microsoft.com/SMI/2005/WindowsSettings";
xmlns:dpi2="http://schemas.microsoft.com/SMI/2016/WindowsSettings";>
<dpi1:dpiAware>true/PM</dpi1:dpiAware>
<dpi2:dpiAwareness>PerMonitorV2, PerMonitor, system</dpi2:dpiAwareness>
</asmv3:windowsSettings>
</asmv3:application>
<compatibility xmlns="urn:schemas-microsoft-com:compatibility.v1">
<application>
<supportedOS Id="{e2011457-1546-43c5-a5fe-008deee3d3f0}"/>
<supportedOS Id="{35138b9a-5d96-4fbd-8e2d-a2440225f93a}"/>
<supportedOS Id="{4a2f28e3-53b9-4441-ba9c-d69d4a4a6e38}"/>
<supportedOS Id="{1f676c76-80e1-4239-95bb-83d0f6d0da78}"/>
<supportedOS Id="{8e0f7a12-bfb3-4fe8-b9a5-48fd50a15a9a}"/>
</application>
</compatibility>

> Mark Windows launcher binary as per-monitor DPI aware
> -----------------------------------------------------

> Key: NETBEANS-1227
> URL: https://issues.apache.org/jira/browse/NETBEANS-1227
> Project: NetBeans
> Issue Type: Bug
> Components: platform - Launchers&CLI
> Affects Versions: 9.0
> Environment: Windows 8.1 and Windows 10
> Reporter: Eirik Bakke
> Priority: Major
> Labels: HiDPI
>
> As of Java 10.0.2, support for HiDPI monitors on Windows is quite good. All
> the standard Swing components appear in high resolution, and Graphics2D
> surfaces are automatically scaled appropriately for whichever monitor their
> containing window is located on, including when windows are dragged between
> monitors in a mixed-DPI multi-monitor setting.
> For this to work, however, the EXE file that launches NetBeans must contain a
> manifest that declares the application to be DPI-aware. Such a manifest
> currently exists in java.exe and javaw.exe, but not in the custom
> netbeans64.exe launcher. A workaround for the missing manifest is to right
> click the "bin\netbeans64.exe" file, or whichever shortcut is being used to
> open NetBeans, go to the "Compatibility" tab, click "Change high DPI
> settings", "Override high DPI scaling behavior", and select scaling performed
> by "Application".
> An appropriate manifest should be added to netbeans64.exe to declare NetBeans
> as per-monitor DPI aware.
> To see how the manifest should be declared, we can dump the manifest of
> javaw.exe:
> {code:xml}
> <?xml version="1.0"?>
> <assembly xmlns="urn:schemas-microsoft-com:asm.v1"
> xmlns:asmv3="urn:schemas-microsoft-com:asm.v3" manifestVersion="1.0">
> <assemblyIdentity name="javaw.exe" version="10.0.2.0"
> processorArchitecture="X86" type="win32"/>
> <description>Java(TM) SE process</description>
> <!-- More stuff goes here. --->
> <asmv3:application>
> <asmv3:windowsSettings
> xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings";>
> <dpiAware>true/PM</dpiAware>
> </asmv3:windowsSettings>
> </asmv3:application>
> <!-- More stuff goes here. --->
> </assembly>
> {code}
> This reveals that Java 10.0.2 considers itself DPI-aware at the "Per Monitor
> V1" level (see the Microsoft documentation linked below). The NetBeans
> launcher binary should declare the same.
