This looks good. I checked with OGL and Metal (project Lanai) on macOS. One question is - do we need to support this test in HiDPI mode? The difference between HiDPI and non-HiDPI mode is that VolatileImage has more pixels and every draw operation use scaled blits. The test in question scales the graphics ourselves. To eliminate the "sun.java2d.uiScale=1" we will need to apply the scale to the BufferedImage size, then we should skip the usage of "getSnapshot", and then we will need to scale all rendering to the BufferedImage(simulating the HiDPI in VolatileImage), but in the end, the same scaled blit will be tested. -- Best regards, Sergey.
