Sometimes, when using the find controller to search something in a web page, there is a visual glitch like you can see in this screenshot: https://cloud.githubusercontent.com/assets/584972/18129498/02efcc0e-6f59-11e6-88bf-a52e6c1baaaf.png You can try a search on this website in order to reproduce the issue: https://fanglingsu.github.io/vimb/ I am able to reproduce this issue in Epiphany 3.24.2 using webkit2gtk+ 2.16.4.
