Try reverting: commit 8e42637050275945200797538a34c13c90b295cc Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue May 21 11:13:03 2013 +0100 sna: Re-enable read-read optimisations Matti, I thought we had closed your ff corruption bugs? Well, at some point were rather rare and extremely difficult to reproduce, but now they seem to have made a comeback. Reproducability is still a question mark, but they occur every once in a while. Tried reverting that changeset, no effect for the Gtk+ corruption depicted in the screenshots at least -- still occurs. *** Bug 64881 has been marked as a duplicate of this bug. *** The big scary change would be the introduction of cow support. To test, you can disable it with: diff --git a/src/sna/sna_accel.c b/src/sna/sna_accel.c index 371abb0..fc82e09 100644 --- a/src/sna/sna_accel.c +++ b/src/sna/sna_accel.c @@ -68,7 +68,7 @@ #define USE_CPU_BO 1 #define USE_USERPTR_UPLOADS 1 #define USE_USERPTR_DOWNLOADS 1 -#define USE_COW 1 +#define USE_COW 0 #define MIGRATE_ALL 0 #define DBG_NO_CPU_UPLOAD 0 Masked by --enable-userptr. Will you stop running on such ancient kernels :-p commit ee7ea10148b7843091c3fa103f9f4476979f8b68 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu May 23 12:55:21 2013 +0100 sna: Only flags the PolyFillRect as REPLACES if it is unclipped Otherwise we discard a fill operation that is required to initialise the pixmap before drawing commences.

Example of corruption
I'm getting this/similar bug on Fedora 20 XFCE
[ 9.229] (II) LoadModule: "intel"
[ 9.229] (II) Loading /usr/lib64/xorg/modules/drivers/intel_drv.so
[ 9.230] (II) Module intel: vendor="X.Org Foundation"
[ 9.230] compiled for 1.14.4, module version = 2.21.15
[ 9.230] Module class: X.Org Video Driver
[ 9.230] ABI class: X.Org Video Driver, version 14.1
Should I open a new bug?
Before you do, you will want to try a much later driver. Upgraded to git, don't see the problem so far |

Created attachment 79630 [details] Corrupted window area in a Gtk+2 app (Pidgin), after a floating "hover notification" box has disappeared, the area under it is corrupted. Corrupted pixmaps (cached, I suppose) all around in Gtk+2 at least, and increasingly in Firefox (latest beta 22.0). Gtk+ corruptions seemed to appear after upgrading to latest GIT version of the Intel driver. Kernel upgrade from 3.8.13 -> 3.9.3 made no apparent difference. Occasional corruptions in Firefox have been around for quite a while (and reported separately), so that's probably another bug entirely. -- Window manager: WindowMaker 0.95.4 -- chipset: 00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 10) -- system architecture: i686 / 32bit -- xf86-video-intel: GIT abe85adda51c58d3f3b9c5dea6cec4b13a65cdcd -- xserver: X.Org X Server 1.12.4-6 from latest Debian testing -- mesa: 8.0.5-4 from Debian testing -- libpixman: 0.26.0-4 -- libdrm version: 2.4.40-1 -- kernel version: 3.9.3 (vanilla from kernel.org) -- Linux distribution: current Debian Testing -- Machine or mobo model: Asus P5KPL-CM -- Display connector: VGA
