The half-blank pages you're seeing is a feature that's recently been enabled. This is a case of latency improvement that visually appears to be worse. When rendering can't keep up with your rate of scrolling, Chrome will display the part that has been rendered so far and display a checkerboard pattern for the not yet rendered part. Previously, Chrome would just flip the display buffers less often if rendering can't keep up.
