Wide LineDoubleDash lines drew black on screen under XQuartz while the server's own XGetImage readback showed the correct pixels, because at depth 24 that readback ignores alpha. Opaque text and dashed arcs take the same path. fbValidateGC widens a planemask that covers the drawable's depth to cover its full bits per pixel, so the blit and fill paths can take their all-ones shortcuts. On a rootless server that also writes the alpha channel of the window's premultiplied surface, which CoreGraphics then composites as black. Rootless keeps that alpha opaque by clearing the bits from the planemask, but only its own ValidateGC does so, and mi revalidates the GC in the middle of a drawing operation to swap the foreground for the background pixel. By then the damage layer has unwrapped the rootless funcs down to fb, so the reassertion never happens and the rest of the operation lands with a zero alpha channel.
