I have just downloaded and installed InDesign from the Creative cloud and found that the various forms of cursor in the 'working area' are excessively large and somewhat pixelated.
I'm not sure if they are meant to be this large...but it really seems unnecessary and is rather irritating me!
I looked for settings to change it but found none...
This is only occurring in InDesign (checked photoshop which is fine) and cursor size returns to normal only for the outer-most toolbars (File, Edit etc. at the top)
Thank you Steve
One of the suggestions in the link you posted worked fine;
Strange how this only effected InDesign, when on the same day I also downloaded photoshop and lightroom from the creative cloud.
