I do not think it is specific to chrome, the bug reproduces with other applications such as Document Viewer.
When I use the scroll wheel in gedit, if I have switched from another application it often jumps somewhere distant in the document instead of scrolling as it should. As a workaround, I use the arrow keys to move the cursor, which jumps the viewport position back to the cursor area so I can scroll normally from there. This is an annoying and persistent problem.
