The demo Shockwave for Director movie shows hardware-accelerated 3D content. If you move the browser window around, that 3D content will spill outside the plugin area, leaving "trails". If you select the demo's "#Software" button the movie will switch to Software rendering mode and will present as intended, switching back to "#OpenGL" mode will again show the effect. Reproducible: Always Steps to Reproduce: 1. If you don't already have it, install Shockwave For Director plugin at http://sdc.shockwave.com/ shockwave/download/download.cgi? 2. Load demo url 3. Make sure that OpenGL is enabled by clicking on the #openGL button. 4. Move the browser window quickly around the screen and observe results. Actual Results: 3D animation of a walking/jumping alien will leave "trails" when using hardware 3D rendering (OpenGL) and moving the browser window. Expected Results: 3D animation should not leave trails.

Mass-unassigning my bugs (I'm working on another team right now)
I am not sure Shockwave for Director is supported by Adobe anymore or not but I think it is not supported on web due to lag of Plugin API such as NPAPI. Since the browser will not resolve "dir" urls like in the URL field but just start download process, I think this can be marked as "RESOLVED WONTFIX" due to removal of NPAPI from browsers.
From Adobe Link - https://helpx.adobe.com/shockwave/shockwave-end-of-life-faq.html "Adobe Director, an authoring tool for Shockwave content, was discontinued on February 1, 2017 and the Shockwave player for macOS was discontinued on March 1, 2017."
