Hey Imre! Pretty nasty bug you've got there. Though it is not a bug within KMail but the underlying graphics driver. I am assuming you are using an Intel chip, so I am going to move the bug over there, if you are not the triagers of that package can toss the bug along.
Meanwhile, please provide the output of the command lspci -vvnn this will make it a lot easier for the Xorg triagers to process this bug. Thank you very much and have a nice day :) ** Package changed: kdepim (Ubuntu) => xserver-xorg-video-intel (Ubuntu) ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: New => Incomplete -- kmail distorts on screen https://bugs.launchpad.net/bugs/375060 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
