Adobe apps window change

Hello dear colleague, I can't say anything on this matter, but I have to say, I noticed that you're working on FAO. I am also a graphic designer in FAO Ukraine. I think we have to stay together to achieve our common solutions.

I've had this issue for more years than I can remember. Never found a fix.

Just a shot in the dark here but are you allowing your monitor to go to sleep? 

I have two ideas to stabilize the way you view your InDesign file (as well as Illustrator and Photoshop):

1) It's much more professional, and gives you much more stability of the way the panels appear in your applications if you turn on the Application Frame in your applications (Window > Application Frame). Then you will view one application at a time. For example, InDesign will look like this, instead of seeing your Desktop and parts of other applications visible:

2) Create one or more workspaces in Windows > Workspace which arrange the panels you're using in the way you need. You can return them to their original position at any time by choosing Reset [Workspace Name] from the workspace menu.

3) If you see strange geometric shapes, you should try turning off the GPU Preference in Preferences > GPU Preference.
