EntityLoader leaks memory with some graphics cards

The example shows that with some graphics cards EntityLoader doesn't release memory when the source is reloaded. This happens with
Intel HD Graphics 4000 (laptop)
Intel HD Graphics 5500 (Broadwell) (desktop)
Intel HD Graphics 4000 (desktop)
while Nvidia Ge-Force 640M 2GB Ram DDR3 seems to release the memory correctly. On Intel RAM usage grows with reloads until
computer freezes.

Tested on Windows 8.1.
