Short description of error
When the Metal GPU backend is used for the Blender UI, then the outline on the image in the video sequencer previewer appears distorted. This issue does not occur if the OpenGL backend is used.
The issue is with the Metal image showing a white line running from the centre of the image to the upper right. This is part of the "Image outline" provided by the Blender UI.
Exact steps for others to reproduce the error
System
tab change the backend to Metal, save the preferences, then close and re-open Blender.File -> New -> Video Editing

Changed status from 'Needs Triage' to: 'Needs Developer To Reproduce'
I can confirm.
This is a case where
GPU_PRIM_LINE_LOOP
is used but not supported for Metal.There are other similar cases (proportional edit circle, snap circle...)
Not sure how this will be handled (#96261 (Metal Viewport ))
Added subscriber: @Michael-Parkin-White-Apple
Thanks for highlighting, should be a fairly straight forward fix. There are cases where Line Loop should be emulated, but generally more optimal and consistent to fix the calling code, as it only involves ejecting one extra vertex.
Will submit a patch soon.
