[Interest] Memory consumption when starting QML application

[Marco Trapanese]

I have a QML application which often hangs during launch. I found the GPU memory usage has a very high peak when my application starts. Then it returns to a reasonable value. If this "peak" is so high to use all the available memory my application (of course!) hangs. This is a known behavior of QML engine or there should be a serious lack in my application? For examaple below are some readings: it starts with 100% free, then drops down to 5 MB (sometimes goes to 0!) and it says there is an "invalid space". Finally comes back to 470 MB free and it will be stable.
