Indesign CC 2017 display issues

Hi,

I have a few issues with the new Indesign CC 2017:

a) while editing text, a thin line appears above the row;

b) when changing text paragraph alignment, the text line appears doubled, both with old and new alignment (for 4 seconds maybe);

c) worst of all, when changing text layout, the next page sometimes doesn't show its updated text-flow. Suspections arise just when selecting text (selection highlight is correct but the visible text is outdated). The text refreshes just when you make a blind change in the text and then undo it.

None of that occured in CC 2015.

iMac 4K (2016), MacOS Sierra.

Pictures attached.

Thanks in advance!
