      Description

      Hello,

      I noticed that Qt builtin animations are cause of very high GPU usage. I attached simple application reproducing the problem. Its app from the Qt Quick App template. Just Rectangle and 2 animations that are changing its opacity from 0 to 1 and from 1 to 0. 

      The application often starts with  1%-4% of GPU usage and after couple of seconds then rise to something around 20%-30%. The problem can be observed on at least 5 different computers with Windows 10.

      Regards
