Bug#979590: libx11-xcb1: Updating to 1.7.0-1 from 1.6.12-1 breaks chromium and google chrome

[Michel Le Bihan <michel@lebihan.pl>]

Package: libx11-xcb1
Version: 2:1.7.0-1
Severity: normal
X-Debbugs-Cc: michel@lebihan.pl

Dear Maintainer,

After updating libx11-xcb1 chromium and google chrome UI is not
responding to any input and clicking anywhere on the app window causes
the GNOME app is not responding dialog to appear. The app actually is
not frozen because if you pass a URL with dynamic web content as a
parameter, it will be constantly updated. I didn't notice any other
affected app, but I didn't test much.
