Graphics rendering improperly after Big Sur update

I recently updated my macbook pro (13", 2017) to Big Sur and it appears that graphics are not being rendered properly in a number of applications. One example is in Excel, where drop down lists created through data validation are not rendered. The lists exist, but they are not visible on the screen, so I have to select menu options blindly. I've encountered a similar issue in other programs, so I am certain that the problem is not Excel. I am running the latest release of Big Sur (11.4), which I updated to from High Sierra. Any recommendation for how to trouble-shoot or resolve this problem would be greatly appreciated.

MacBook Pro 13″, macOS 11.4

Are there any AntiVirus, Disk Cleaner, Optimizers, Defrag, VPNs etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal operation of the OS and may even Corrupt the OS requiring a Reinstallation.


There are no known Viruses in the wild that self replicate and affect macOS. There are Malware and Adware that does affect macOS and are often times downloaded as part of an Application from Third Party UnTrusted Site and get installed along with the Application.

Good to know and thank you for clearing that up.


Suggest downloading the Application Etrecheck directly from a Trusted Developer and well Respected ASC Contributor. The application is free or paid from added features. Run the application with Full Disc Access ( Security & Privacy - Full Disc Access ). It will take a Snap Shot -  both the hardware and software. The Report will Not Reveal Any Personal Information. Post back the Full Report - copy and paste - using the Additional Text Icon ( 3rd Icon to last )


We can have a look at the report for possible issues and may have possible suggestions to resolve the issues.
