I get this when I open a PDF in Acrobat Reader after the first click. All my video drivers up at latest version as is Acrobat Reader.
Is it likley to be a bug with Adobe or with the video card driver?
We are sorry for the trouble and the delay in response.
Is this a behavior with a particular PDF file or with all the PDFs that you open? Please try to open a different PDF file and check. If its a file specific issue please share the file with us for testing.

Also, please check for any necessary and recommended updates for the video drivers and firmware and try removing them and reinstalling and see if that helps.
Let us know how it goes
Thanks for your suggestions. I checked my Adobe Acrobat Reader DC version and it's the latest, 20.006.20034. I've also checked the (Radeon) video driver version and it is the latest too.
I get this behaviour on most, though not 100%, of PDFs, including those I generate and many received or downloaded from various places on the internet.
We are sorry to hear that the issue still persists. lease try the following steps and see if that helps:
Go to Adobe Acrobat / Reader DC (Mac), Edit (Windows) > Preferences > Enhanced security > Turn Off the Protected mode and uncheck the enhanced security > Click OK and check.
Note: Please turn on the security after testing.
If it still doesn't work, try to create a new test user profile with full admin rights or enable the root account in Mac and try opening the PDF there and check,
Let us know how it goes
If the issue is still unresolved, please try the following steps and see if that helps:
Please try to update the application to the new version 20.006.20042 released recently. Go to Help > Check for Updates. Also, share the video card driver version and try to update the video drivers and firmware.
If it still doesn't work please share the sample files and the log files with us for testing.
