Upgrading to XR Plugin from VR Settings has broken text masking in build

Unity Engine

After upgrading to the new XR Plugin system text now overflows in build where it didn’t before and doesn’t in editor.

We’ve tried changing all of the sittings, custom size fitters, upgrading the text to TMP, and tried upgrading to Unity 2020.2.7 from 2019.4.19 and no difference is made.

The project is using HDRP 7.5.3.

Text in editor/previous builds:

The issue is present using either OpenVR XR plugin or MockHMD.

Freshly created canvas objects with default settings have the same issue.
