Same here! We have that phenomenon on 2 Macs and not on 3 others... all same specs... (all 27" iMacs)
So I guess it's some software issue-conflict and not hardware...
It's specially ennoying when you try to scale complex objects (eg. copy-pasted from Illustrator), because it renders all the single elements one at a time for every step...
Unfortunately we sometimes get such files from clients to proccess for prepress...
It never was an issue till now. Just a VERY big waste of time because of that bug.
We were not able to pin it down yet.
This is fixed in the latest updates and has to do with GPU use, if you turn of use GPU in your preferences in a older version it will also go away. But simply update to the latest version may be better ;-)
Nope, not fixed here with ID 184.108.40.206 on a Mac Pro (End 2013) running El Capitan. On this machine with two AMD FirePro D500 3072MB it isn’t even possible to switch GPU on or off.
But I found out that the »strange animation« thing as well as other bugs (i.e. alt-click on a picture > edit in Photoshop > save in Photoshop > return to Indesign > crash) has something to do with the »Informations« panel. If this panel is NOT visible, everything works! Adobe should fix this, as the informations palette is important (i.e. checking picture resolution).
Ah yes, you are right. This is indeed known but should be fixed. When scaling groups or multiple items like a group you will see this when the info panel is open, should have realized that in answering you as well.
Let's hope it'll be fixed soon, I need the info panel open...
You're absolutely right! Thanks!
