@Randy Roberts‚ mentioned that Acrobat plugin 126.96.36.199 in Chrome causing display issues (but Safari and Firefox are ok since no such extension available), so I'd suggest you try one of the latter two (or turn off the plugin, if you have it).
We had this issue yesterday with one of our people. If you go to Start Menu>Settings>Personalization>Colors and turn off dark mode for apps it should fix it.
https://one.workfront.com/s/article/Workfront-Some-pages-in-Workfront-have-a-black-background suggests it's also linked to the Acrobat extension. Support pointed us to https://support.apple.com/en-us/HT208976 for resolving on the Macs.
This dark mode on the Mac does not affect browser content, it only affects the top and left side bars on browsers. The Acrobat plug in bug has nothing to do with dark mode on the Mac or Windows.
