I assume the webkit bug applies to Ventura. I’m running Monterey.
New info:
Fails: s=120 https://avatars.observableusercontent.com/avatar/82811927da99f8938001b2ef1f552ad2c47083e46ebc55a3a146a5a5848c4519?s=120&format=avif
Succeeds: s=119 https://avatars.observableusercontent.com/avatar/82811927da99f8938001b2ef1f552ad2c47083e46ebc55a3a146a5a5848c4519?s=119&format=avif
Any other value than s=120 succeeds. Weird.
The avatars are marked as immutable for browser caching, so it’s possible that for a specific avatar you’ve got a bad copy cached. Maybe try emptying your cache and then reloading the page.
Martien, we will keep an eye out to see if others encounter the same problem. Really weird.
Thanks!
Even weirder: same computer, different user: same symptoms.
As I said before, this is likely a Safari bug that’s specific to your macOS version. Did you try what I suggested earlier?
I certainly did, but you’re right, I got swamped by the flood of messages. Even when filtering for Safari and avatar and such it gave me no clue whatsoever. I leave it for what it is. I guess it will be gone when I upgrade to a new Mac with Ventura or Sonoma.
It seems fixed?! Symptoms have magically disappeared. Don’t know why. Using same version of Safari Version 16.5 (17615.2.9.11.6, 17615).
Weird magic.
Case closed.
