Yeah, I’m on iOS 17. Weird though, not happening in any other sites nor Discourse forums.
This is where I’d put the video I recorded of going to try.discourse.org and twittercommuntiy.com to show the bug not existing there, but it’s still very slightly flickering. Might be a bad beta 4?
Although on the flip side I’m not seeing it on sites like devforum.roblox.com or forums.unrealengine.com. I’m not sure what the difference between the sites are which is determining the impact here, but it seems like you’re probably right.
