REVISION SUMMARY
  The shader self test uses GLRenderTarget and restores the viewport. Due
  to the setVirtualScreenGeometry not being set the calculated viewport is
  incorrect and any rendering breaks. This is a regression introduced with
  https://phabricator.kde.org/rKWIN1708278a451e6dab92549f9cabe6ad13ea3b4ba2 which only affects Wayland
  backends which do not perform per screen rendering.
  
  The glxbackend was not affected as it sets the viewport on screen
  geometry change.
