--- Comment #6 from Paul Bodenbenner <paul.bodenbenner at gmail.com> --- I get the same problems as described before with two different monitors. Using an up-to-date Arch Linux with kernel 3.14 (also tried kernel 3.15rc2) with a hd3470 card. Problem occurs only, if an external monitor is connected at resolution 1920x1080 at 60Hz in single mode (extended mode makes no problems). Funny enough when using 1920x1080 at 50Hz in single mode everything seems also fine. By switching back to Catalyst the problem doesn't occur. Found some similar threads: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1209315 https://bugs.freedesktop.org/show_bug.cgi?id=42621 By disabling color tiling and dpm the phenomenon appears only when switching between modes (monitors on / off). So in this case when starting the laptop with closed lid everything is ok, until switching between modes. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
