Cropped off markers when exporting figures as PNG

Hello,
I have run into an issue where seemingly randomly - though probably only at the periphery of graphs, circular markers are cropped off leaving arcs when exporting to PNG. I've attached one example of code and produced figure below - I have not tested if any of the messing with the defaults is critical in producing this - just set them how I generally like my figures. I'm using OpenGL, which I believe is part of the problem since I don't recall having these issues when working on a hardware accelerated system. Running 9.2.0.556344 (R2017a) on Win7 64-bit i7 system with Intel HD 530 graphics - attaching sysinfo png.
Best regards,
/Jonas

Your issue can be resolved by changing either the resolution (DPI) or the renderer.
Try the following code:
% do not use opengl
print cropcircledemo.png -dpng -r600 -painters
% use any other dpi
print cropcircledemo.png -dpng -r700

Thanks Michael! I would call these work-arounds, but I'll still accept the answer - hopefully later Matlab versions will improve the handling of this - don't believe it used to behave like this.
