In the safari 17 beta the output of Offscreen Canvas WebGL contexts appears to be mirrored vertically compared to Chrome and Firefox. Is anyone else encountering this issue?

That sounds like a bug. Can you use Feedback Assistant to file a bug report, and paste the FB ID here? To launch Feedback Assistant on a non-Beta build, type this URL into Safari and hit/tap Return, then allow the app to be launched: applefeedback:// Note that your iCloud account needs to be registered as a developer, although there should be an option to do that for free through <https://developer.apple.com/>.
