Side by side screenshot of text rendering on Eclipse 4.3 and Eclipse 4.2.1

I just downloaded and tried a nightly build of Eclipse 4.3, on OSX Mountain Lion, in order to verify the fix for issue 388574. 

That issue was indeed fixed, but I noticed that the IDE as a whole looked pretty bad; in particular, the fonts were blurry. When I zoomed in it looks like the fonts are rendered at a lower resolution or perhaps the LCD subpixel aliasing wasn't right.

I'm not actually sure what the problem is, but I pulled up my other (4.2.1) Eclipse right next to it, and zoomed in. I've attached a screenshot of what I see; Eclipse 4.3 is on the left, Eclipse 4.2.1 on the right.  The contents in the two windows aren't identical (I have different projects in the two workspaces) but you can see the font rendering on the right (4.2.1) is much crisper.

(Note: This is on a Retina macbook, where I think there is some compatibility handling for apps to deal with the higher resolution.)

Did you actually start Eclipse with high-resolution support (see bug 382972)?
Comment 3 Tor Norbye CLA 2012-11-07 16:21:07 EST
No, that's probably the issue -- I just downloaded a nightly build (to verify an unrelated fix) and started it the same way I start downloads of the stable release, and unlike 4.2, fonts didn't look right.
Comment 4 Tristan Hume CLA 2012-11-08 14:12:43 EST
High resolution mode has not been enabled yet. You have to implement the plist fix in bug 382972.

Once all major bugs related to retina displays have been fixed retina mode will be enabled. In fact I stumbled upon this bug while looking for unfixed retina bugs.

This bug should be closed as a duplicate of bug 382972.
