Never found a solution for my main computer, but it works everywhere else I try it, which means it’s specific to my hardware. If you’re facing the issue on multiple computers, then it’s probably not hardware-related, so we’re dealing with different problems.
All the drivers are up to date. Not sure what the issue is, then, but it’s apparently not directly a WordPress issue, so I’ll have to follow up elsewhere. Thanks for the help!
What the blork? I tried it in playground, and it still doesn’t work. So I brought up that page on a different computer, and it works fine. So it’s something to do with my computer or the graphics card. What could possibly be doing that?
I really appreciate the suggestion. But now I’m confused for a completely different reason! Any guesses there?
