There are more strange things. First, swapping the screen connections physically did not change the behaviour. I don't think the crtcs would get swapped too but I am not sure. The primary screen is not rotated, the secondary is. Window last mapped on primary screen (or the secondary when I turn off rotation) keeps capped by the screen refresh rate when unmapped. Window last mapped on rotated screen is not capped when unmapped. It seems that screen blank behaves like unmap, at least for glxgears. Since the screen no longer paints and the gears are synchronized to the screen after unmapping they sometimes stop painting too.
