Screen turns to black and white dots using Adobe Acrobat Reader DC 19.21.20049

[Hiro-Toki]

Please help me about the screen noise like mosaic problem as bellow.

This is the screen when I just opened the file.

When I click on the screen, noise appears.

If I change the zooming, it will disappear.

But if I click on the screen again, noise will be shown again.

My PC condition

Windows 10 Home 64bit

Acrobat Reader DC 19.021.20049.27333

I already installed latest patch (19.021.20049 Optional update), but it didn't work.

Hi Amal. Thank you for your reply.

This behavior occours for every PDF.

And I updated latest version now, but sitll happened.

> Would you mind sharing the exact workflow or steps you are doing?

I just installed Adobe Reader DC.

But I think I had been using with no problem before.

It happened suddenly.
I'm not sure the cause is from Windows update or DC update.
FYI, my OS is Japanese version.

Version 1903
OS Build 18362.476

Hi there,

Download the process monitor tool here (https://docs.microsoft.com/en-us/sysinternals/downloads/procmon) run the process monitor tool and then open the PDF file to reproduce the issue and collect the log files and share them through private message. 

Click on the message icon on the top right corner of the screen to start the private message with us.

Hi There!

I am having the same issues.  When I open a document it looks fine, if I click into it, it turns "mosaic", unreadable and un-editable. 

I have tried all the suggestions above, and still having issues.  When I uninstall and open document using Edge, it opens fine.  

Thanks,

Julie

We have seen the same problem on Lenovo Thinkpads T495 with AMD Radeon Vega 8 integrated graphics and updating to the latest graphics driver 20.3.1 didn't help.

Hi Vuiu,

I have just seen a post from MarkInFL with a solution that worked for me.

This is from his post:

"Here is the fix:
Right-click on your Acrobat Reader DC icon on the desktop or navigate to the AcroRd32.exe file in this folder
C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader

Choose "Troubleshoot Compatibility." Tell the troubleshooter to run this program in Windows 7 compatability mode.

It now works perfectly. NOTE: AcroRd32.exe is a 32bit program -- that's why it's in the (x86) folder. For some reason, Win10 won't run it properly."

Please see the full post and give him a like if it helps, you can find it here: https://community.adobe.com/t5/acrobat-reader/screen-turns-to-black-and-white-dots-using-adobe-acrob...

Take it easy ;0)
