I forgot to mention the steps to reproduce the bug, and the precautions to take :
* open the project in QGIS 2.14 ( I have not tested with older versions) * open a terminal and use this kind of command to monitor QGIS memory consumption : htop, or ps with watch -n1 'ps -aux --sort -pmem | head -5' * Navigate through the project by zooming in and out, pan, etc. I think you emphasize the memory leak by displaying the layer at small scale ( with many buildings displayed) * Be aware that this will increase the memory, so keep an eye on the memory consumption so that your system has enough free memory to work properly.
