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) --- ApportVersion: 2.14.1-0ubuntu3.6 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: kwin CurrentDesktop: KDE DistUpgraded: 2014-08-06 14:32:56,683 DEBUG enabling apt cron job DistroCodename: trusty DistroRelease: Ubuntu 14.04 DistroVariant: kubuntu DkmsStatus: virtualbox, 4.3.10, 3.13.0-40-generic, x86_64: installed virtualbox-guest, 4.3.10, 3.13.0-40-generic, x86_64: installed ExtraDebuggingInterest: No GraphicsCard: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02) (prog-if 00 [VGA controller]) Subsystem: Dell Device [1028:0428] InstallationDate: Installed on 2011-01-10 (1407 days ago) InstallationMedia: Ubuntu 10.10 "Maverick Meerkat" - Release amd64 (20101007) MachineType: Dell Inc.
