The following article claims that DPI virtualization of not DPI–aware

I just tried to set dpiAware=false in the java.manifest file on my Windows 7
and the whole Java application was scaled.
It looks like that for platforms from Windows Windows 8 and higher the fix
JDK-8076545 can be reverted because the Windows OS can automatically scale an
application.
The fix JDK-8076545 needs to be reverted for Windows Vista and higher. In
other case the Windows L&F font will be smaller in Java app because the fix
scales it size down.
It will be smaller ? But isn't that the bug - that it is too small ?
Don't try to change the dpi aware property but provide before and after
screenshots of at least win7 and win8.1 (not win 8) or later with 125% scaling.
[1] - Windows 7 scale 125% before the JDK-8076545 fix (original large
Windows font)
Left window - Windows L&F, right window - Metal L&F
[2] - Windows 8.1 scale 125 % before the JDK-8076545 fix
[3] - Windows 7 scale 125% after the JDK-8076545 fix (large windows
font is re-scaled to scale 100%)
[4] - Windows 8.1 scale 125% after the JDK-8076545 fix
[5] - screenshots with 150% scale on Windows 7 and 200% on Windows 8.1

There are following requirements for the Windows font scaling:
Windows 7 and 8.1 scale: 125% - large Windows L&F font - required
feature (JDK-8157838)
Windows 10 scale 300% - huge Windows L&F font - incorrect behavior
(JDK-8152980)

Thanks,

For Windows XP the fix JDK-8076545 needs to be reverted to take the
personalized windows font into account.
I run SwingSet2 on JDK 8u with the dpiAware=false option on Windows 7 with
scale 150% and Windows 8.1 with scale 200% and found nothing wrong with it.
As I understand, the fix JDK-6829055 Update application manifests with new
Windows 7 dpiAware section
was just an improvement.
Should I remove the dpiAware option from the java.manifiest file in the current
fix as well?
Thanks,
Alexandr.

But my point is that on Windows 8.1 the "125%" font setting is no longer a font
setting as such.
Either the *whole* app gets scaled, or *nothing* get scaled, so the user
complaining about
this bug would not have seen his request honoured in the same way as is on
Windows 7.
Or is setting dpiaware causing us to continue to get "XP Style" scaling as it
is known.
Disabling that manifest entry and reverting to using API is something we should
also be considering
but I don't know that this bug is the place to address that change which may
cause more problems
as well as fix some ..

From what I read on the web Windows Vista, 7, and 8, Windows uses this setting
to scale just
the fonts, but for 8.1 and 10 it is a whole application scale, so perhaps
rather than just
revert the fix, you can make it OS version dependent ?
To allow the Windows OS scale a java application we need to revert the fix
which sets dpiAvare=true in the java.manifest file. See JDK-8080153 Cannot
disable DPI awareness.

Surface Pro devices are not going to be running Vista or 7 .. and I expect most
are running
Windows 8.1 or later by now.
Of course you will need to find a way to test this hypothesis : probably on a
windows 10
desktop with 125% scaling to see what happens with the Win L&F.

Hello,
Could you review the fix:
bug:https://bugs.openjdk.java.net/browse/JDK-8157838
webrev:http://cr.openjdk.java.net/~alexsch/8157838/webrev.00
This is the regression from the fix JDK-8076545 in the JDK 8u.
There was a request JDK-8152980 to backport the fix to JDK 8u because a text size
is very big on Windows 10 with UI scaling set to 300% when the Windows L&F is
used.
However, this leads to another issue that a personalized Windows font size is not
taken into account in Swing app with Windows L&F on JDK 8u.
JDK 9 does not run into this issue because it contains support for HiDPI
displays which reads the system DPI and scales a whole application with fonts
according to system UI scale.
The proposed solution is just to revert back the initial JDK-8076545 fix for
JDK 8u only.
Thanks,
Alexandr.
