Closed as invalid.

I've got fresh installs of QGIS with this same rendering issue. I think 
this ticket needs to be re-opened.

Note 10 in that ticket (http://hub.qgis.org/issues/8231#note-10) describes:

"The problem only occurs when the "Improved Polygon Capturing" plug-in 
is enabled in the 32-bit version and there are PostGIS layers in the 
document - a fairly unique situation, which explains why it wasn't 
occurring for you. We will simply disable this plugin when not being 
used, and your help troubleshooting is much appreciated. Hopefully this 
plugin can be fixed by its creator so other users don't have the same 
issue. Thanks again!"

But I'm not sure if that's the cause. I've been sporting spatialite for 
a while now =)
