I'm still getting this with Chromium (Version 25.0.1364.160 Ubuntu 12.04 (25.0.1364.160-0ubuntu0.12.04.1)) running KDE. This only seems to happen when I have a large number of tabs open (about 150 at the moment, but I think I've seen it happen with less), having been running Chromium for over a day.
I have put together an ugly fix for the problem of the persistent windows - the following is a shell script that uses xdotool to hide any window that is clicked. This means that the menu shadow can be hidden without closing Chromium. --- #!/bin/sh id=`wmctrl -v -r :SELECT: -e dummy 2>&1 | grep Using.window | grep -o 0x[0-9a-fA-F]*` xdotool windowunmap $id --- This script requires wmctrl and xdotool, which can be installed via apt: > sudo apt-get install wmctrl xdotool -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/868841 Title: right-click/context menus freeze and won't go away To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/868841/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
