Research direction

Review commit 6964eb2 and Wine bug 60399 first, then check whether the change applies cleanly to Proton’s Wine tree. Done means the fix is backported and native ARM64 Unity OpenXR no longer crashes during tracking-origin changes such as recentering or putting on the headset.

Description

Could you pick 6964eb2 into Proton’s Wine?

It fixes an ARM64 __CxxFrameHandler3 crash triggered by UnityOpenXR on Steam Frame (proton-11.0-2c).

Details and reproducer: Wine bug 60399.

Edit: This affects native ARM64 Unity OpenXR games during tracking-origin changes, such as recentering or putting the headset on.
