JDK-8305648 - Support Canvas rendering
Description
Blend mode changes are not reflecting on screen when application is ran on metal pipeline. The objects are getting rendered with default blend modes.
This issue was observed while running the RenderPerf test on metal pipeline.
This issue can be reproduced by running following 3 tests:
-CircleBlendMultiply
-CircleBlendAdd
-CircleBlendDarken

Screenshot of the CircleBlendMultiply test on both ES2 and metal pipeline is attached for reference.
