While scrolling through a relatively large file with the blame turned on I sometimes see white gaps on the ruler on the left side. When I hover over the line with the gap it reveals a proper blame hover and when I move the mouse back to the middle of the editor the decoration shows up properly.

This is happening to me with the latest version of chrome.

Is there a public git repo and specific file you can identify to use to repeat?

I haven't been using this on a public repo but here's a set of steps to try to reproduce it in a local environment:

1) Set up a Go development environment
    -Download the Go SDK from http://golang.org
    -Create an empty directory for your GOPATH
    -Set your GOPATH environment variable to this location
2) Create a $GOPATH/src/github.com/sirnewton01 directory
3) Unzip the provided zip into that directory (should create a godev directory)
4) "go install github.com/sirnewton01/godev"
5) "go get github.com/jacobsa/oglematchers"
6) Run the godev command from $GOPATH/bin/godev and open up chrome on the URL it prints to stdout
7) Navigate to github.com/jacobsa/oglematchers/equals_test.go
8) Invoke Blame in the editor
9) Scroll up and down a little bit looking for white gaps in the blame
10) Hover over the white gap and notice that there is some blame there and when you unhover the decoration is shaded properly

It appears to be a heisenbug because I can't seem to observe the problem while trying to debug it.
