Created attachment 259828 [details] screen capture of bug I've been digging a plugin rendering problem of Win port, which is not-rendering the bottom or right edge of flash contents in some situation. After some investigation, I got to suspect the subpixel positioning of widgets and found a related layout test, hidpi-content-inside-iframe-leaves-trails.html. I modified this test little bit to reflect my circumstances(iframe left = 0.5, foo div left = 0.5), and it shows a problematic result, the repaint area is not covering the whole area of the changed element. I've tested and seen this on Safari8, Win and WinCairo port's WinLauncher. Can anybody look into this?
