Broken Transparency on Ubuntu 10.04
Reported by jamin.th...@gmail.com, Jun 13 2010 Back to list
Chrome Version (from the about:version page):
Is this the most recent version:
OS + version: Ubuntu 10.04 Lucid Lynx
CPU architecture: 32-bit
Window manager: Compiz

What steps will reproduce the problem?
1. Mouse over an item to get a tooltip
-or-
2. Drag an image with transparent background
-or-
3. Drag tab out of browser window

What is the expected result?
All of these items should have some kind of transparency surrounding them

What happens instead?
The areas that would normally be transparent are filled with black

well this seems bad...

did this work for you with 10.04 in a previous version of chrome, or did upgrading to 10.04 cause the problem?
Comment 3 by javier...@gmail.com, Jun 14 2010
As the other bug report says, chromium .408 doesn't have this issue on 10.04.

can you bisect the regression? previous builds available for download here:

Comment 5 by javier...@gmail.com, Jun 15 2010
I started bisecting but noticed that this is apparently not occuring on the official builds. Maybe this is a regression introduced by the ppa builds ? I'll open a bug for them on launchpad so they have a look at it.

ok thanks. Can you post the launchpad bug link here so we can track their progress?
Yup, I can confirm that as well. The issue is nonexistent in the official builds.
Comment 8 by f...@sofaraway.org, Jun 15 2010
just tested some of my ubuntu builds: recent dailies are all affected.
latest -dev (6.0.427.0~r49010) is affected too.
previous -dev (6.0.408.1~r47574) is *not* affected.

bisecting my dailies between 427 and 408 gave me this:

6.0.424.0~svn20100603r48800 NOK
6.0.423.0~svn20100602r48687 NOK
6.0.423.0~svn20100601r48614 NOK
6.0.422.0~svn20100531r48583 OK
6.0.420.0~svn20100529r48550 OK

so it's between r48583 & r48614... and guess what.. I introduced two changes at that point:

+  * Change StartupWMClass to Chromium-browser in the desktop launcher so
+    cairo-dock does the right thing (LP: #587664)
+    - update debian/chromium-browser.desktop
+  * Set XLIB_SKIP_ARGB_VISUALS=1 in the wrapper to prevent flash from dying
+    with a Gdk-ERROR when gtk2 is built with RGBA support (like in Maverick).
+    (LP: #584959)
+    - update debian/chromium-browser.sh

and indeed, dropping XLIB_SKIP_ARGB_VISUALS fixes it.
problem is it's really needed in Maverick.
I can sure limit that workaround to Maverick only but the problem will remain there.

It sounds like they reverted the RGBA change in Maverick.
Comment 11 by f...@sofaraway.org, Jun 20 2010
yep, but it will be back.
in the meantime, i've dropped XLIB_SKIP_ARGB_VISUALS completely from my daily builds (but not yet from the other builds)
I can confirm that all the issues are gone on the ppa's daily builds.

Thanks!
Hi, 

I have the same problem (or similar) and using: 6.0.472.51 (Official Build 57639) beta
Where can I get a version without the issue?
