The issue appears when clicking on a menu item from the top of chrome, and if there is a list then the blue highlighting of each item as the cursor moves down only highlights every second item instead of every item as normal.
I have had this happen in the past but was unsure which package was the culprit. I don't know from the above list which package update may have been responsible, but since the same effect has been seen on 4 different machines I presume it is likely kdebase-workspace? This is with KDE as the desktop environment, and with all packages up to date. Has anyone else seen this issue and if so is there a workaround or is it a known bug. It is an odd one to google for but presumably I am not the only one who has seen this issue. The version of chrome is chrome stable google-chrome 36.0.1985.125-1
Thanks.

I am experiencing something slightly different in Chromium (still wrong though). I think these issues are related to the change from Gtk to Chrome's built-in UI.

I had a similar experience recently as well (though with Chromium). Clicking a menu and hovering over an item caused the item (background and text) to be bleached white. I suspected Gtk initially but it seemed to resolve itself for me. I checked my recent updates and the only things of note were a couple xorg-server and video driver updates.

In my case chrome was working normally prior to the pacman updates that I listed, and then changed as in my first post as soon as the updates were installed. I did check that rebooting made no difference. But since it was working before the updates and chrome itself was not updated I was puzzled as to the cause.

I'm also seeing the same menu issue. Not only that, but the chromium performance in general is terrible when the window is maximized in KDE. Pages take a long time to load, tabs switch slowly, text highlighting is slow, all javascript driven stuff is slow. Only when the browser window is maximized and only in KDE.

I have exactly the same issue as mcloaked. Downgrading to kdebase-workspace-4.11.10-2 resolves it, so (as suspected) the issue lies with kdebase-workspace. I don't know how to triage better than this, though!
Offline
Thanks martinc2, downgrading kdebase-workspace resolved the issue for now.

I wonder if it is worth trying to get some diagnostics and putting in an upstream kde bug report? However I am not sure what diagnostics I can get for this issue in terms of a log file?

I have no idea what the root cause is but if you turn off compositing (Alt+Shift+F12), it'll stop. You can use the Window Rules KCM to make a rule that'll automatically stop/start compositing when Chromium is started. Sadly, this is a poor workaround as you lose all the niceties that compositing brings You can also change KWin's render mode from OpenGL to Raster but that's too intrusive for me - I'd rather just disable compositing as a whole. I'm using a laptop with an HD4000 set to use the default SNA acceleration.

Yes you are right - Alt-Shift-F12 works around the problem with the alternating highlighting. Maybe a bug needs to be filed against kdebase-workspace? As you say this workaround takes away the nice features of desktop effects.
Edit: Reported upstream at https://bugs.kde.org/show_bug.cgi?id=338434
and at https://bugs.archlinux.org/task/41647
If anyone can add input to the two bugs it would be helpful.

There is now progress on this - check the kde bug report referenced above.

It's much appreciated for taking the time to open that bug. Indeed, after running the commands given there in #5, I can now run Chromium without turning off compositing.
Offline
Hooray! I can confirm the fix on the kde bug works for me too. Thanks mcloaked!
Offline
I am marking this as solved here in this thread although I will wait to see if there is an upstream fix in an updated kdebase-workspace package before closing the upstream bug report, and the arch flyspray report.
Edit: The upstream bugs are now closed.

Just upgraded to KDE 4.14. and this is still working poorly. I've searched the Arch rollback machine for that particular kdebase-workspace version with no luck. Anyone with a direct link?
Offline
A new version kdebase-workspace-4.11.11-2-x86_64.pkg.tar.xz was pushed to the mirrors this evening at just before 1800.

Neky, the previous version of the package is available in the Arch Rollback machine archive at http://seblu.net/a/arm/packages/k/kdebase-workspace/
4.11.10-2 appears about 11 lines down the list.

Hey, thanks for digging that link up for me, I was trying to find the package by month/week/day which is tiresome. Seems like the yesterdays second update (around 6pm) to that package fixed everything.
