Hello XR community and especially HoloLens developers -
A significant bug was reported on Unity 2020.3.21f1 LTS affecting projects targeting OpenXR and HoloLens 2.
We have identified the root cause and will release a fix in the upcoming 2020.3.24f1 LTS patch update, targeted for later this month. Until its release, please be aware that users running 2020.3.21f1, 2020.3.22f1, and 2020.3.23f1 and deploying to a WMR or HoloLens 2 device will experience this issue.
Additionally, we know that this is a very unpleasant bug for some users. We are also taking steps to improve our internal workflows to mitigate this type of regression in the future.
Thanks,
The Unity Team
