      Description

      I am working on Quick Controls 2 application for RaspberryPi3 where I have a line chart being updated by timer (0,5 sec) with real FFT data.
      When I switch my application to Quick 2D renderer then all available memory is leaked very fast. As soon as I switch back to OpenGL renderer then the problem disappears. I am using environment QT_QUICK_BACKEND=software to switch to 2D renderer.
      I tried with EGLFS and LinuxFB backends: same results.
