i have the following problem and it is really bothering me and stressing my workflow.
I use two screens. One of them is a 4k monitor, the other FullHD. In the windows appearance settings i use a custom dpi setting of 185% for textsize.
As soon as i start indesign with the "scalable user interface" acticated windows produces an error an deactivates the aero effect. When move explorer windows from one screen to the other i feel like working with windows 95 all the time, due the the deactivated windows aero theme.
Now, if i deactivate the scaling of the UI in indesign it works. But you cant work in indesign without scaling the UI on a 4k monitor. Everything is way to small.
If i just set the textsize dpi to 100% it also works. Then i can work in indesign but the windows text and icons are super small. Not good either.
My system is running a core i7 6700k with 32GB RAM and a Geforce GTX 980 Ti... Windows should never tell me that it doesnt have enough resources!!!
Known issue with Windows 7. You can have Aero or you can scale the UI.
I recommend moving to Windows 10, anyway.
Thanks for the feedback.
I was afraid of this answer. I would switch to win 10 if all of my software would work. Sadly it does not. As of now i guess i will deal without Aero...
