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