A family of Microsoft word processing software products for creating web, email, and print documents.
Thank you for the extra details. Since the flickering happens mainly in the Print window and also when you are working in tables in Word, it sounds more like an Office display or printer-related issue than a normal mouse setting.
Kindly set another printer as the default temporarily, such as Microsoft Print to PDF, and then test again. .
If you use a physical printer, try updating or reinstalling its driver from the printer manufacturer’s website.
Run an Online Repair for Office from Control Panel > Programs and Features > Microsoft 365/Office > Change > Online Repair.
If possible, test from another Windows user account. If the issue does not happen there, the problem may be related to the current Windows profile.
Please keep me posted.
