Mike Gorchak to Sam Hello Sam! You have reverted back my patches for OpenGL renderer :) To reproduce an issue, compare graphics output while running these tests: testdraw2 --renderer opengl --blend mask --cyclealpha and testdraw2 --renderer software --blend mask --cyclealpha You will see, that software renderer output is different from opengl renderer output. Thanks!
