DPI Scaling on retina display

Does anyone else have an issue on the specular tab where the options and preview window is missing?
I think its something to do with my scaling (My display is 2480 x 2160) then i scale windows to 200% for the icons etc to look correct and give me a good amount of screen space (im running a laptop with 15" screen)

The first image is my screen, the second is a screenshot from the Articad tutorial.

Thanks


Thanks,
Luke

Don't know if this helps you at all Luke -

A workaround that i  found was to right-click on the boxes and select/tick  'Right to left Reading order' then untick it. This allows you to see/edit the values. Not ideal but i don't change them often enough for it to be a bother.
