Quality assurance plan to ensure Flash content on Windows with asyncDrawing enabled is ready for public release.

Quality Criteria

Risk area Requirement Status
Flash videos and apps No significant regression in site correctness, video performance or app/gaming performance 49 Total Bugs, 7 Open (14.29%), 2 Blockers remain
General performance Overall performance of asyncDrawing enabled Firefox Adobe Flash Player should not be notably worse than with asyncDrawing not enabled TBD

Testing summary

Scope of Testing

In Scope

The scope of our testing is the async drawing functionality and performance of the most popular sites and games with latest Adobe Flash Player.

  • Integration: Verify the integration with the current browser functionalities and UI;
  • Functionality: Basic and advanced functionality to be verified according to the existing requirements;
  • Performance: Reference, where applicable, observed and collected performance data.

Out of Scope

We will not be testing on obscure web sites nor in conjunction with popular add-ons

Requirements for testing


Testing will be performed on following OSes:

  • Windows 10 (64bit and 32bit)
  • Windows 7

Bug Triage Spreadsheet - Includes results from various SoftVision testing rounds and analysis.

[1] All open bugs triaged against both settings. Any bug that was reproducible in both modes removed from bug lists.

General Performance

Acceptable regression ranges, if any, need to be determined through testing. In general, where slow path bitmap based painting is in use (wmode=windowless) we have always had performance issues. As such those sites do not play into our decision making here. We now convert all flash that defaults or is set to use window mode, to direct. In general we haven't seen major performance issues on these sites.

Criteria Description Metric asyncDrawing disabled asyncDrawing enabled Criteria Met? QA Owner
CPU usage (observed) Average % CPU results results PASS tracy
Memory usage (observed) Peak memory usage results results PASS tracy
