What happens if you are using a mouse?
Can You please follow the workaround related to turning Off the preferences mentioned at unknown
InDesign CC 2017 slow. If that does not work please share your file with me, i need to investigate further.
You can share with me at firstname.lastname@example.org
Thanks in Advnace.
Hi Michael, I'd never tried it with a mouse but having just attached my old Magic Mouse, it's exactly the same problem using a mouse as the trackpad.
Just in case it helps anyone, I appear to have located my problem and it seems a bit obvious now.
It was lag when using a second monitor. If InDesign was open in my bigger screen attached via HDMI, it lagged.
If I dropped it back over onto my laptop screen, the lag was gone.
Any experiences of second-screen lag for anyone...?!
