  1. Resolution Note (fix version 3.0.6):

    This fixes an issue with sorting of the canvas sort order and graphic depth properties. There was 2 issues happening here. The original fix was supposed to compare canvases up the chain to make sure drop-downs worked correctly. The fix assumed the blocking sub-canvas sorting order was always obeyed, but did not consider additional depth, so it would early out. This fix removes the original workaround and allows all raycast results comparing from the TrackedDeviceGraphicsRaycasters, but does an additional priority sort against the canvas sortOrder first before comparing depth.

    We (myself and the company I work for, Engage) found a potential fix for this, by making some changes to TrackedDeviceGraphicRaycaster.s_InteractorRaycasters, converting it into a HashSet instead of a single reference to a raycaster. So far the results has been good, but not sure if this could have other side effects, so take it under your own responsibility.

    As of version 2021.3.24f1, XRIT 2.3.2: UI poking stops working randomly when two active canvas are too close.

    One of the interactions that Apple is going to introduce to Apple Vision Pro is being able to interact with your fingers like Poking. It's really a shame that we wont be able to have this on other devices alongside because of this bug, please fix it....please....

    Thanks for all the concern. It’s on our radar, unfortunately still no eta for the fix however.

    Well, it's that time of the year again. You know, moment where you're so close to launching a new feature only to realize that there is a bug in unity preventing you from doing what you need to or preventing it from working everywhere. (Cross-platform who?) ...oh shoot it's only January 3rd...well if we're lucky it will be fixed in the next release, or before the end of the new year, or maybe never... 🥹 here's to dreaming 🤞
