    Description

      Some change in dev (5.7) causes serious issues for render-to-texture widgets: run the qopenglwidget example on xcb with 5.6 and dev. Then move the cursor around above the slider and other widgets. With dev the frame rate of the QOpenGLWidget drops drastically while hovering (as this triggers repaints in the backingstore).
