When you move your head around, the image seems to tear or split. This does not happen in M57 (57.0.2987.117) so it seems to be a new regression.

What steps will reproduce the problem?
Start with Daydream as the default headset
(1) go to https://try.matterport.com/virtual-reality/webvr/ and scroll down to select the Hawaiian Oceanside Villa
(2) Select the vr icon in the bottom right hand corner and follow DON flow prompts

What is the expected result? head movement happens without distortion to the image

What happens instead? The image seems to tear or split in a couple places briefly when you move your head around.

Note that this was logged originally in crbug 703378 but that bug spawned off into another issue. So re-logging this one.
