I see the distortion in Mozilla Thunderbird and also Forefox, see attached screen shot The workaround from comment 1 seems to help, but I should test for some more days. ** Attachment added: "Screen shot from distorted Thunderbird window." https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1178982/+attachment/4427917/+files/Grafik-Fehler.png -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1178982 Title: My Dell Dimension desktop shows purple/green and distorted Flash video unless acceleration method is changed Status in linux package in Ubuntu: Invalid Bug description: 1. Lubuntu 13.04 / Linux 3.8.0.-19-generic 2. I do not know and can not check as the computer in question is no longer in my possession Flash does not play movies properly, resulting in a purple/green screen that is completely out of proportion. Happens mainly on Dell Dimension computers with an Intel chipset: http://ubuntuforums.org/showthread.php?t=2132368&p=12641898#post12641898 One user reported falling back to an older Kernel as a workaround "I did find the following workaround. When booting, I choose the Advanced Ubuntu options and pick either Linux 3.5.0-27-generic or Linux 3.2.0-40-generic. With either, the video/flash is fine. The default kernel is Linux 3.8.0-19-generic, and that is the version where it does not work" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1178982/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
