Setting blend ports to anything non-Replace will corrupt the GL_ALPHA_TEST_REF value, essentially forcing it to 1.0. This is perfectly fine inside QC, but when using QC to render on NSOpenGLContexts that involve non-QC rendering, it can lead to problems.

test.qtz

Compile with gcc -framework Cocoa -framework Quartz -o qctest Then, run in the same folder as the test.qtz file.Again, not a big deal, but if your app uses QC for compositing on an externally managed OpenGL Context, this might be pertinent to you.
