      Description

      Rendering of multiple instances of a framebuffer object leads to degraded render performance on Wayland platform. The similar effect does not happen on other QPA's like xcb or eglfs.

      Steps to reproduce:

      1. Run the compositor in attached example project qmlscene compositor.qml
      2. Execute the application with Wayland  ./qquickviewcomparison -platform wayland

      Expected result:

      1. The animation runs smoothly on three framebuffer object.

      Actual result:

      1. The animation performance is heavily impaired and frame rate goes down to 5-8FPS.
