Testing suggesting it's not very application-dependent: 1. With Libre started and 'flickering' occurring, kill -9 it and make sure it's dead; flickering persists while using Firefox.
2. From that state, conduct 'change mode and revert' workaround: flickering stops and does not recur after restarting Libre (prior to letting display sleep happen at least). [Also noting I am likely to give up on this and drop a Radeon 6450 card in as throwing different hardware at the problem is going to be cheaper than the time-cost. Still interested in seeing it resolved to the extent that it's regressive and also always farcical when the hardware requirements for word processing outside of vi arbitrarily go up.] -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1181355 Title: R300 (RS480): Intermittent flickering corruption top half of display (VGA, 1080p) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1181355/+subscriptions _______________________________________________ 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
