I'm not sure about Swingmark but RenderPerf tracks the real content rendering (there are color marks for each frame that are rendered after the bunch of primitives and the java robot detects the change of the color marks). So, we can trust the numbers in the RenderPerf. > Probably we can force metal to draw some initial surfaces w/o using > DisplayLink? It could work but complicates things a bit. I'll see what we can do here. Meanwhile, I'll provide the solution that we discussed earlier. ------------- PR: https://git.openjdk.java.net/jdk/pull/5373
