      Description

      To reproduce:

      1. Build and run the attached code, it is a modified qmloscilloscope example
      2. run pmap

      Current behavior:

      • the memory allocation grows constantly and after a minute it starts to affect the fps

      Expected result:

      • the memory consumption would stay on the same level like the qmloscilloscope examples

      Note:

      • if no labels are displayed it still grows
      • if opengl is turned of it still grows
      • valgrind shows no memory leaks
