--- Comment #17 from Thomas Lübking <thomas.luebk...@gmail.com> --- Thanks, that may contain "tearing" not sure, could be the recording, but the key problem is that briefly a black frame appears. Since this also happens w/ xrender compositing, it's not the buffer_age usage of kwin - is the problem constrained to the (firefox) window or does it cover the entire screen as soon as (firefox) is up? Reg. uxa ./. your touchpad: there should be no direct relation whatsoever, but uxa may cause more CPU load, making the system less responsive in general. Removing the file should restore the status quo ante, but you need to restart X11 in addition, of course ;-) Can you please attach Xorg.0.log from a session where the intel conf snippet was still present?
