Indesign CC 2018 (oct): display of frame borders offset by 1 pixel
Indesign CC 14.0.1 x64, german
put a pageitems' left border exactly on X=0, aligning the item to the left side of a right page on facing pages... see screenshot...
Frame border is displayed offset by 1 pixel.
This does not apply to right aligned items on left pages. Here the frame border is displayed fine.
It's minor ... but ugly.
