Original Redmine Issue: 16385
Affected QGIS version: 2.18.4
Redmine category:map_canvas
QGIS 2.18 new install. One particular project crashes out instantly when trying to move the map canvas, or freezes. This is a fairly simple project with about 15 layers, only 5 of which are active.
One layer appears to be problematic - it is a polyline shapefile (saved out of QGIS from a DXF ASCII 2010 that I imported). This is styled by category (about 40 categories) of which maybe 2/3rds are active.
I created a fresh project & added the layers, testing the zoom as they were added and it was stable until I was just putting the finishing touches to the Composer when it started crashing out .
On advice from the OSGEO list, I removed all the plugins & these projects still crash.
