First of all great work! Makes life a whole lot easier.
Now to my issue. I'm experiencing strange blurry font when using QCP with OpenGL enabled. As far as i can tell, only the appearance of the y axis label ( yAxis->setLabel(label) ) is affected by that. The situation improves a little bit if i use setNotAntialiasedElement(QCP::aeAxes, true), but still remains. See for yourself: http://imgur.com/a/Fp8xK
It just shows the interaction demo with added setOpenGl(true). It is a bit annoying to look at escpecially when using different font colors. Except for this artifact everything is working for me.
Is anybody else experiencing similar issues or does anybody have a clue what could cause this behaviour and how it could be fixed?
