This only happens on my notebook's display.

A potential fix is to enable background caching:
mGraphicsView.setCacheMode(QGraphicsView::CacheBackground);
Impact on performance and potential side effects have to be assessed before implementing this.

Background caching has the side effect that the background is not correctly panned and zoomed. If we clear the cache on pan/zoom, performance is negatively affected.
The root cause of the white lines beneath the bounding rect of components is still unknown, changing the bounding rect and/or item shape does not fix the issue.
