Bug: Shadows disappear on Windows 10 explorer windows
Adobe Acrobat DC keeps turning off the shadows of my explorer windows. Changing the theme in Acrobat doesn't help.
Workaround if you encounter this problem:
- Windows key + r
- Run: sysdm.cpl
- on Performance -> Settings
- Under Visual Effects tab -> Show shadows under windows -> Apply
Probably repeat after restarting Acrobat

I had been experiencing this issue after installing DC last week. As a workaround, I created a shortcut on my Desktop to:

I wish Adobe would listen and fix this! I just update to version 20 and it still does it. . . .
Adobe is ignoring this problem for well over 3 months. The only way Adobe will understand is when we vote with your legs.

I have had the same issue. The action that causes the drop shadows to disappear is opening the Comments (previously Annotations?) tool in the right sidebar.
There is also a lengthy discussion on the Adobe forums:
In this discussion it seems that opening PDF files in separate windows rather than in tabs also causes this issue to occur.
BTW, another easy way to access the performance settings is to search for "Performance" with the Windows search bar. You should get a hit for the Performance Settings (and it will remain under the "Settings" tab of the search results, at least for a while).

Have had this problem for over a month now - erased all Adobe, reinstalled, repeated - no change. Am going into Performance / Setting / Show shadows 10 or 20x / day. It's absurd for this kind of software. When will Adobe listen + fix?

This really needs to be addressed!
I currently have "open documents as new tabs in same window" enabled and it still causes this issue.
For me, this problem is very easy to reproduce.
Shadows are turned off every time I open "Annotation" tool. It may not be the only cause of the problem but I think it's a good location to look at.

I've had this issue and even with tabs, it still does it... insane
I have seen several people report that having DC open PDFs in tabs solves this issue for them. It does not work for me unfortunately.
I had always used the tabs settings from the beginning (it is on by default). I have toggled it back and forth, the shadows are always removed when I open a PDF.
I am on Windows 10 Version 1903 Build 18362.476. If you're on a newer version and the tabs setting fixes the issue for you, can you let me know?

Took me quite a while to figure out what is causing that problem. As said, reapplying it is not a really good solution. I realized though that this only happens if you do not open the PDF documents in Tabs. If you go to Settings and enable "open documents as new tabs" then it does not happen.
Not perfect though...

Indeed, I faced the same issue. Workaround do not help very much. Re-applying the shadows under "Visual Effects" tab only works until Acrobat opens a new PDF file. It is very inconvenience to re-apply the shadows after each PDF file.
