We just fixed a bug where sites with unusual settings (don’t retrieve size of images) had problems with images causing scroll jump as the images resized. We have removed this setting since it was a “shoot yourself in the foot” setting. Maybe check and see if you had that enabled.

The other possible culprit is advertisements.

Basically anything that causes the viewport to dynamically resize will cause huge problems.
