Bug 35075 – Painting glitch following selection

• Status: RESOLVED
• Resolution: WONTFIX
• Component: Layout and Rendering

[Eric Roman]

After selecting text on a page, the blue selection area does not fully get repainted, causing blue artifacts to be left on the screen.

This is very reproducible using a particular webpage with webkit nightly:

(1) Navigate to
    http://www.comodo.com/home/internet-security/browser.php

(2) Click on the "Frequent Questions" tab in the middle column of the page.

(3) Select a text range starting from "Frequently Asked Questions about Comodo", and dragging down a couple paragraphs.

(4) Click anywhere else on the page to cancel the selection.

(5) Now we are left with blue artifacts on the page.

Image attached showing what it looks like.

This happens for me in WebKit nightly (r54921).

In vanilla Safari 4.0.4 (5531.21.10) it works fine.

Also happens for me in Chrome 5.0.307.7

I tried to find this URL on Wayback Archive but the earliest is from 2011 and it is about not able to find URL:

Since we don't have reproducible test case.

Marking this as 'RESOLVED WONTFIX'.
