[Pkg-chromium-maint] Bug#704922: chromium: Screen corruption with Adobe's flashplugin

[Adrian Knoth]

Package: chromium
Version: 26.0.1410.43-1
Severity: normal
Tags: upstream

Let me copy&paste the upstream bug report:

Chrome Version (from the about:version page):Version 26.0.1410.43 Debian
7.0 (189671) 
Is this the most recent version:
OS + version: Debian unstable
CPU architecture (32-bit / 64-bit): 64bit
Window manager: fluxbox
URLs (if relevant): http://issuu.com/gimpmagazine/docs/issue3
Behavior in Linux Firefox: renders correctly
Behavior in Windows Chrome (if you have access to it): renders correctly

What steps will reproduce the problem?
1. Install Adobe's flashplugin, 11.2.202.275 as of now
2. go to https://github.com/jackaudio/jack2 or any other repo
3. hover over the "copy to clipboard" icon

What is the expected result?
Icon being highlighted

What happens instead?
Arbitrary video memory content being displayed

The same happens if you try to read the gimp magazine (URL mentioned
above) when hovering over the pages.

Google Chrome (same version, same system) on Linux is not affected.

Tested on two different systems with three different graphics drivers
(radeon, nouveau and NVIDIA 310.44). Verified by others.
