I'm having an issue in QGIS print composer. I am using QGIS 2.18.
Some of my legend items are displayed in low resolution or are partially cut off. The strange thing is that some groups of the legend are affected, others not, although they are using the exact same symbol and symbol size etc. I have tried en-/disabeling the auto-refresh button, created a new legend from scratch and also refreshed several times using the blue refresh circle button (F5). I cannot get it to work though.
