Description zdro 2009-02-18 21:50:13 UTC 
I just changed the JDK for netbeans from 1.6.0_02 up to 1.6.0_12, and all of the fonts are slightly BLURRY.  It's
subtle, but noticeable.  I thought there was something wrong with my eyes at first, but my other applications looked clear.

I've attached two screenshots showing the difference.

Any guidance would be greatly appreciated.  I can't edit like this...

I just tried this with the latest dev build, just to make sure that it's still an issue.  It is.

Also, the font I'm using is Bitstream Vera Sans Mono 10.

I would like to add that I am experiencing this issue on Vista as well.
Comment 5 Ondrej Langr 2009-11-13 07:45:44 UTC 
Guys, can you please help me to assign this to the right component please? A JDK problem? Maybe related to Issue #175407?

Comment 7 Antonin Nebuzelsky 2010-10-04 09:51:29 UTC 
There were fixes introduced in JDK 6u10 related to font rendering on Windows.

http://www.oracle.com/technetwork/java/javase/6u10-142936.html

e.g.

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6591278
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6599742
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6597822

Can you try the following two flags (in separate runs of NetBeans)?

-J-Dsun.java2d.d3d=false
-J-Dsun.java2d.noddraw=true

See more info at

http://download.oracle.com/javase/1.5.0/docs/guide/2d/flags.html

(you can set these properties either on command line or in netbeans.conf file
in your NB installation)

Also can you try with the latest update of JDK 6 (without any additional options) and confirm if you see / don't see the blur?

Thanks.

Finally found JDK bugs describing the problem for two different Nvidia GeForce graphics cards:

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6769144
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6593715

The first bug is specifically related to changes in 6u10. Please provide information about your graphics card in the Comments field in the bug #6769144.

Closing wontfix on our side.
