Can you please keep expanding that list of broken applications until I have a match... ;-) Sorry, i am failing to do so in much detail, i only have these additional applications where i were able to reproduce this bug: Kdevelop -- using text editor in this IDE is almost impossible as any keypress thre makes many GUI element to "blink". I think qt-creator will have the same issue. Gimp -- some menus are becoming invisible but current selected item, but this is rare. I've kdevelop under awesome with TearFree enabled. Typing is fairly busy, but I am not noticing a flash of broken rendering. Is there any chance you can grab a screencast or record a movie? (A picture is worth a thousand words when it comes to trying to spot relevant differences between setups.) Found (I guess) a similar issue using vncviewer: commit 46256fa5a0ca4230ae7c226781c78c525e2648c6 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Dec 5 16:12:22 2013 +0000 sna: Pass MOVE_READ for partial TearFree move-to-gpu When fixing up a pending shadow pageflip for TearFree, we must tell it that it needs to flush the damage for a partial move-to-gpu. Even though the current area does not read from the destination, the move-to-gpu callback is a global pass, and we need to assume the worst for the region outside of the target. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=72343 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> How does everything fare applying that patch? I had similar issues with blinking and stuff ( mentioned in https://bugs.freedesktop.org/show_bug.cgi?id=68410#c77 ). They seem to be fixed now, nothing blinked anymore using the git version for a day. commit ade25f4f95994b565a8ed8eb3811ff7453a8b0e5 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Mon Dec 9 10:49:56 2013 +0000 sna: Only discard READ hint for TearFree copy iff it subsumes the pixmap Remembering that the target window may be smaller than its backing pixmap.

With Option "TearFree" "true" in xorg.conf as in Section "Device" Identifier "Card0" Driver "intel" BusID "PCI:0:2:0" Option "AccelMethod" "sna" Option "TearFree" "true" EndSection latest git version (on the moment of this report this was bd22abee8f33b20ff6bc7297b0a9ae8708d18727 commit on master branch) of xf86-video-intel is producing "blinking" effect for parts of application with complex GUI with lots of elements, when they are getting updated and redrawn or obscured by mouse cursor. When "TearFree" is commented out -- all works flawlessly. Only complex GUI applications like IDEs, or IMs (e.g. IntelliJ IDEA or Skype) are affected, simple ones (like terminal emulators) are working fine even with TearFree set to true.
