HI @fagi,

I did log this issue with the team as I have seen it once in AutoCAD for Mac 2018.  I noticed however that the screen captures you provided are from AutoCAD 2016.  Are you running this in High Sierra? If so, this version of AutoCAD for Mac is not yet supported in that OS but there will be a patch available shortly to change that.

AutoCAD/LT for Mac 2017.2 and 2018 are both designed to run in macOS High Sierra.
