Bug 48018 – [chromium] DRT assertion failure with compositing/geometry/outline-change.html

• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

[Kenneth Russell]

The layout test compositing/geometry/outline-change.html when run in DRT/NRWT (--platform chromium-gpu) is causing the following assertion failure. I am unable to reproduce the assertion when running DumpRenderTree manually with apparently similar command line arguments. Need to understand why this is happening.

The now seems to pass on all GPU platforms:
