QtCharts fuzzy when openGL enabled on retina displays
I am using QtCharts (from v5.9 release) for a real-time oscilloscope type display on iphone and mac-os. I have found that line charts appear fuzzy with openGL enabled on high resolution display (like retina on iphone or mac). If I disable openGL it becomes very clean (not fuzzy).
Is this a known issue? Is there any work-around that I can apply?
