Widget Components set to screen space do not render in the correct position with low engine scalability settings after upgrading to 4.8 from 4.7

I widget component that has been set to show in screen space will not render in the correct position of screen. It will be offset. This appears to happen after a project has been upgraded from 4.7.6 to 4.8

1. Open the attached project
2. Upgrade it to 4.8.1
3. Click play in Editor
4. Notice the progress bar does not seem to move (Stays over the top of the gray box)
5. Stop PIE
6. Set the scalability settings to low
7. Click Play in Editor
8. Notice that the progress bar is not floating over the same block that it was before

Expected: the Bar would float over the top of the gray box even in low scalability settings
Result: the Bar appears to move around with a strange offset
