Bug 406153 – Artifacts when scrolling in chromium.

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description Brandon Singer 2012-02-28 14:10:10 UTC]

I get a some artifacts when scrolling in chromium. However, this only happens when scrolling a little bit at a time (scroll wheel, arrow key) but scrolling with page up/down does not cause this problem. But this does not happen when scrolling on some pages like gmail. Having a fresh profile and only one tab open at a time does not fix the problem either.

In version 17.0.963.56, it only happens a little bit on a few pages. But in newer versions like 18.0.1025.33 and 18.0.1025.33 it happens a lot on almost every page. A screen shot of what I'm seeing: http://tinypic.com/view.php?pic=333hl5d&s=5

Can you repro with google-chrome? If so please file an upstream bug (http://new.crbug.com) and post the link here.
