I have an issue with my Abode Acrobat Reader DC with version (20.006.20042). Everytime when I opened a file, it can be readed normally but when I wish to copy the words from the PDF file. The PDF file corrupted just like the images below.
It is fine when I was using Adobe Acrobat XI Pro to open the same file so it seems to only affecting Adobe Acrobat Reader DC. I had tried re-install the program and updated to the latest version. Even I used Adobe Acrobat Reader DC to open other PDF file, it's still the same problem.
Anyone has the same issue with me? My laptop is running Windows 10.
I have exactly the same screen render bug in Adobe Acrobat Reader DC 2020.009.20065 on Windows 10 Home Version 10.0.18363 Build 18363
Like the OP, my documents render perfectly fine until I attempt to select a line. Then the document view corrupts.
I do not have this problem with opening documents in Edge, Chrome or Opera.
Graphics card is a Radeon 5700 XT. Issue spans the life of many updates to the screen drivers.
I have no idea how to fix this annoying problem.
I have the same problem happening when I attempt to select text (PC, Windows 11 Pro, Acrobat Pro), I'm glad to have found this thread because it never occurred to me that the graphics card might be to blame.
You see, I'm generating my own PDFs, and I was worried I was doing something wrong.
I will try opening the file on another computer to see if the issue persists.
