I searched / googled / binged for this, and I seem to be the only developer on the planet with this problem, I have been living with it for years, but it affects my performance.
If I Search File on eclipse, 3.7.2 on Centos (but this happens on all of my installations, on all OSs) with a relatively large set of results (50+ files), the tree displays normally, but the filenames aren’t showing. (PHP and other perspectives).
Usually I see a triangle arrow, a character (file / dir) and line number arrow plus the file name.
When the result set is large, I get everything except the file name ... If I click the arrows, they open the correct file / line, and the properties of the elements (files, dirs, etc.) are perfectly displayed when right-clicking.
Clicking on the error log in the installation details does not give an answer, but otherwise the IDE works fine.
Any tips on where to look for debugs / fixes would be appreciated.
Here is a screenshot ...
