[BUG] SteamVR Home flickers when reprojecting on AMD

[amalon]

Describe the bug SteamVR home flickers in both the VR View window and the headset. It appears that occasional frames aren't scaled to fill the view, resulting in the left & right eye views being composited on top of the previous view but the wrong size (see screenshot).

Render resolution is set to Auto Switching steamvr home to legacy reprojection makes the problem stop. It often seems to stop or reduce after a little while. Not observed in other programs.

To Reproduce Steps to reproduce the behavior:

1. Open SteamVR and wait for steamvr home to show

Expected behavior It should never flicker
