In an effort to restore them as much as I could, I used a combination of waifu2x ("Single-Image Super-Resolution for Anime-Style Art using Deep Convolutional Neural Networks"), Clip Studio Paint resize/cleanup tools, and manual cleanup done by hand.

Have you tried using Diplay Driver Uninstaller to perform a clean wipe of all display drivers that have been installed and then reinstall the most current driver for your card? There could be some reminants that are causing an issues from years of updating. You can get the program free at guru3d.com. Source: 7 months ago

Decent chance. But it's conceivably a driver issue. Try reverting to an older driver if you're on the latest. Run DDU (display driver uninstaller from guru3d.com) first. Source: over 1 year ago

If you cannot access that website, then try guru3d.com, you can find it from there too. Source: over 1 year ago
