Reopen per comment 7.
I've done some investigating and it seems this is a problem specifically linked to the EGit plugin, not SWT itself. The labels that you see with the white backgrounds are created different than labels in SWT, and therefore have irregular colors. As far as this bug report is concerned everything is working as expected.
This is one of those cases where something started working properly, and exposed other issues which previously weren't noticeable.
