Fullscreen misbehaving, Mac
I'm not sure if this is an issue with Mac (OS X El Capitan, 10.11.6) or Acrobat (Adobe Acrobat Pro DC, 2018.009.20044), but if i put Adobe Acrobat Pro is in fullscreen mode it will occasionally pop out of it and appear in the current view. I have not been able to recreate the issue in an accurate way, but I've mostly noticed it whilst chrome is loading pages in a new tab, but it's also happened with other programs like the finder. If I'm viewing another program in fullscreen mode when it happens Acrobat appears infront, blocking my view. It's quite a nuisance. I made a screen recording of it happening, though as I mentioned I'm still not sure of exactly what triggers it.
This happens to me exactly as described. It pops out and goes behind something or sometimes infront of another full screen app.
I cant say if its Chrome related because I always have Chrome running for something or the other.
We are able to reproduce the first issue - Acrobat pop out of fullscreen.
But we are still not able to reproduce the issue in which Acrobat pops out of fullscreen and appears in front of something.
If possible we can have a session to check exact steps where you are getting the issue.
I've tried it some more now. If I open Acrobat, put it in fullscreen, and then start Chrome; Acrobat will pop out of fullscreen and appear behind Chrome (like the first thing in the screen recording). This happened every time I tried it now, but only for Chrome. I also tried it for Word and Safari without issues. If Chrome already is open and I just open a new window everything seemed to function as normal and Acrobat stays in full screen. The thing where Acrobat pops out of fullscreen and appear infront of something else in fullscreen is less frequent. As mentioned I've mostly noticed this whilst a page is loading in a new tab in Chrome.
We tried reproducing the issue with the help of screen recording shared by you but we are unable to reproduce it.
Could you please tell what is the frequency of the issue and some other steps due to which this issue is occurring?
