Windows 11 Pro, i9-12900, NVidia 4060 GPU, 64GB memory, Office 2019 - ordinary desktop system.



I recently installed an NVidia 4060 Platinum, BUT I ALSO recently installed the Windows 23H2 update, and I'd be far more suspicious of that, than I am of the GPU change. But I COULD be wrong.


Word works fine when writing, then at some point - maybe a half dozen lines, it doesn't quite show where the cursor is, sometimes is hides the last letter written, or a partial or entire line goes blank but if you move the cursor over the line it returns. Or when erasing, it doesn't show what's being erased - possibly hiding a letter or section of text. It's difficult to describe, but extremely annoying...


And yes, the new GPU is COMPLETELY up to date and using the current STUDIO drivers. As is Windows.


Rebooting hasn't made any difference and I haven't found any settings in Windows that would seem to have anything to do with how Word would work.


The system has been checked for any viruses or malicious software, including running the MS Safety Scanner software, and there's nothing.


If anybody has a rational, reasonable idea, please let me know.
