On lower performing machines where reprojection is constantly used, the user is able to rotate their head faster than the compositor is able to keep up. this allows the user to see outside the rendered image and into the \"hidden mesh area.\"\r\n\r\nThis issue has always existed with Asynchronous reprojection due to how the technology works. In the past, it was harder to notice as there was ample padding around the user's vision to hide the artifacts.\r\n\r\nThe may 14th SteamVR Beta build(1526340843) included optimizations which trimmed down the padding around the visible area as a trade-off for a general performance improvement(3% on Vive, 7% on Vive Pro). As a result, it is easier for the end user to trigger the issue by turning their head quickly.\r\n\r\n**Repro Steps:**\r\n1. In the SteamVR settings, make sure asynchronous reprojection is enabled and interleaved reprojection is disabled.\r\n2. Launch a graphically intensive game such as Arizona Sunshine.\r\n3.  Set the in-game graphics settings far above your computer's capabilities, causing asynchronous reprojection to constantly be on.\r\n4. Rotate your head quickly while observing the outside edges of your vision.\r\n\r\n**Expected Result:** The edge of the render area cannot be seen even if Asynchronous reprojection is turned on.\r\n**Encountered Result:** The edge of the render area can be seen if the user rotates their head fast enough while asynchronous reprojection is turned on.\r\n\r\n**Config Details:**\r\nIssue is not machine or specification specific.\r\n\r\n**Build:**\r\n```\r\nSteamVR Public-250820\t(BuildID:2884151)\r\nSteamVR Beta-250820\t(BuildID:2967062)\r\n```"}}
