Pico 4 - Controller velocity is wrong

[iam4k33m]

Bug occours in Half Life Alyx, and likely any game that uses hand velocity in a similar way for throwing objects.

Description

Objects are thrown with a 90 degree offset on velocity, which changes direction with different controller emulation selections

I can confirm that right now in Alyx all grenades are thrown 90 degrees to the right.

But it worked somehow before in Alyx and it is still working as expected in H3VR. So i guess its more a Alyx and/or SteamVR problem than a general Pico4 or ALVR one.

ALVR 20.5.0

I suspect it could be an issue with Pico OpenXR. Some unity standalone games experience this issue too.

I restarted ALVR and SteamVR and could play Alyx again without this issue. When I encounter it again, I will preserve the log. There was no update of any software in between.

In my experience, Half life alyx level loading leads to wrong throw direction.

Then this just sounds like an Alyx bug then.
