The GPU is drawing 60 times a second regardless of whether the page is static. Not sure how they do their streaming to the GPU, but there will be state changes every time you scroll, or click a button, etc., even on a static page.

There is a difference between drawing the frame into the frame buffer, and scanning the frame buffer out to the display. If you application is coded at all sanely, only the latter is happening at 60 Hz with a static page.
no, the GPU is refreshing the video output at 60Hz, the graphics are not being redrawn at 60Hz in your typical GUI application. Games are a special case of course.
The specs for my mobile GPU say that it has 1024 cores. Wouldn't it be surprising if they were all fully active regardless of workload? (It seems like low-hanging fruit for making a laptop GPU energy efficient.)
