Fuzzy Text

After installing, Netbeans is fuzzy and strains my eyes.  Couldn't find anyone else with the problem.  See attached screenshot
Comment 1 Libor Fischmeistr 2012-11-02 07:05:19 UTC

can you tell us, what DPI do you have? You can find it in Control Panel\Appearance and Personalization\Display - There are three options - 100%, 125% and 150%

I bet you have something higher than 100%.
Comment 2 Libor Fischmeistr 2012-11-02 07:06:43 UTC
And I can confirm your bug, I have the same problem too on Win 8 with increased DPI.
Comment 3 Stanislav Aubrecht 2012-11-02 08:43:32 UTC
Please provide JDK version info and reopen.
Also try running some plain Swing application to see if the problem can be reproduce there, thanks.

NB on Win 8 + Swing app

I have JDK 7u9. The ordinary sample swing application is shown well, but also it seems that this app doesn't care about Windows DPI settings - screenshot.

That Swing app is using Nimbus L&F which uses OpenGL for rendering (guessing from the app output). 
Please try running NetBeans with --laf Nimbus switch and also try running that Swing app with Windows l&f (you may need to tweak its initialization code).

NetBeans witn Nimbus L&F

Here you are. NetBeans with Nimbus L&F. The text is still blurry.

Swing app with Windows L&F

And from the second hand, the simple swing app running with Windows L&F...
Comment 8 kpheasey 2012-11-02 14:40:49 UTC
Changing the DPI to 100% then restarting the computer fixed the problem.  Thanks!
Comment 9 Stanislav Aubrecht 2012-11-02 14:44:29 UTC
Doesn't seem to be Windows 8 specific. If I increase text size to 150% in Windows 7 control panel NetBeans look blurry as well. Also some native apps look blurry.
Strangely enough plain Swing app started from NetBeans looks crisp...

Comment 11 Stanislav Aubrecht 2012-12-03 10:53:39 UTC
-J-Dsun.java2d.dpiaware=true does the trick.
Comment 12 Stanislav Aubrecht 2012-12-03 10:57:05 UTC
We can fix this bug either by adding -J-Dsun.java2d.dpiaware=true to netbeans.conf or by modifying .exe launchers, see here for more details:

Libore, please evaluate, thanks.
Comment 13 _ gtzabari 2012-12-03 16:13:37 UTC

I believe declaring the app to be DPI-aware is only half the work. The other half is getting Netbeans to use the correct font size for different DPI settings. If you stick to the existing behavior the font will look too small on high DPI environments.

NetBeans when text is enlarged by 150%

It does work, NetBeans pick larger fonts as expected.
(Except for non-editor tab headers which should be easily fixable)

The switch is needed only when using 64-bit launcher (netbeans64.exe). When running netbeans.exe a new Java process is created where the DPI settings are correct out of the box.
Comment 16 Libor Fischmeistr 2012-12-05 09:08:56 UTC
The necessary switch added to netbeans.conf

Fix in changeset:
