M, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please run the following command in the development release from a Terminal as it will automatically gather and attach updated debug information to this report:
apport-collect -p xorg 1354841 Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information. Thank you for your understanding.

I couldn't find any event in the systems logs that could explain that. I can "stop" the bug by changing the anti-aliasing options in the system settings (enabled / disabled, level of hinting) and restarting the applications, but the squares can come back later on, and I have to repeat the operation. The bug almost exclusively happens with firefox and thunderbird, though krunner is also affected (but not other kde apps). I'm not using many GTK applications, but I can also see the bug with unison. It used to happen in 13.10 as well, and upgrading to 14.04.1 hasn't improved the situation ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: xorg 1:7.7+1ubuntu8 ProcVersionSignature: Ubuntu 3.13.0-32.57-generic 3.13.11.4 Uname: Linux 3.13.0-32-generic x86_64 ApportVersion: 2.14.1-0ubuntu3.3 Architecture: amd64 CurrentDesktop: KDE Date: Sun Aug 10 14:03:25 2014 InstallationDate: Installed on 2011-01-10 (1307 days ago) InstallationMedia: Ubuntu 10.10 "Maverick Meerkat" - Release amd64 (20101007) ProcEnviron: LANGUAGE= PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_GB.UTF-8 SHELL=/bin/bash SourcePackage: xorg Symptom: display UpgradeStatus: Upgraded to trusty on 2014-08-06 (3 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1354841/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
