Does the backend matter? I'm getting a non-tiled mesh under QT_API=pyqt5 ETS_TOOLKIT=qt, whereas under wx (works with Python 3 only, and may or may not crash silently with Python 2, see below) or under QT_API=pyqt ETS_TOOLKIT=qt4 it is both, meshed and tiled.

Jul 06 23:40:05 linux kernel: python2.7[8735]: segfault at f0 ip 00007f122e3c6452 sp 00007ffeaa7e95f8 error 4 in libgdk-3.so.0.2404.4[7f122e3a7000+79000] (= 3.24.8-1ubuntu1)

EDIT: Actually, I cannot close the preference window in Mayavi2 under the wx backend. If I change the default behaviour in traitsui/wx/file_editor.py:125, then yes.

I see the warnings are being related to #288, also #287 for a similar PR and some discussion.
