I hope you are doing well. I am sorry for your experience with Acrobat Reader.
Is the screenshot you shared with a specific file or with all of them? If this is with one particular file, it could be with the way the file was created.
Would you mind sharing the file with me so that I can check on my end and investigate further?
You may also want to update the application to the latest version and check if it works better. To download, please click the link: Adobe - Adobe Acrobat Reader DC Download | Free PDF viewer for Windows, Mac OS, Android
Let me know if it helps.
Thanks for your reply.

Look forward to hearing from you.
