 Issue 870442  has been merged into this issue.
All these tests in the test suite are really slow [1], and these two in particular:

BlendingWithRenderPassWithMaskColorMatrixAA_GL
BlendingWithRenderPassShadersWithMaskColorMatrixAA_GL

Vladimir, can you please help triage this?

Looks like all of these tests are really slow, and often cause try job failures.  I wonder if they can be sped up, or the time limits increased.
