On the kernel side, I have 3.10.1, and on X server side I have Ubuntu ppa of xserver-xorg-core 1.13.4~git20130508. I'm not sure when exactly it started (could be months ago). Switching to UXA makes the issue in bug-intel-ddx-4.png go away, and probably in bug- intel-ddx-3.png, but that one is a bit harder to reproduce. I'm using mostly GTK2 clients on LXDE environment, without compositing.

I first saw it when entering text: the garbled long, horizontal rectangle changed as I typed (my typing was a part of it and/or near it). Like the reporter of this bug, the rectangles often appear as if the width does not match the contents, causing offsetting/slanting of the pixel lines (perhaps just one effect). It's just been the past few weeks or less (approx.) that I remember noticing it. I am on xf86-video-intel 2.21.13-1 (Arch Linux), and kernel 3.10.2, but I do believe I saw the issue with kernel 3.9.9 as well (and I know I saw it with xf86-video-intel 2.21.12-1, also). It happens at seemingly random times, and often I just see a random rectangle (mostly in Chromium) with the garbled contents, but it goes away quickly when something changes. The rectangles sometimes look different than described above, but I suspect it is the same cause. I'll try to get a screen capture next time I see it. I'll attached my Xorg.0.log file, in case that is of help.

At the moment, we will allocate a staging buffer to perform the copy. My feeling is that we are missing some barrier around that staging buffer and the GPU reads garbage instead of the updated content from chromium. So if switching to userptr does fix the corruption, I think that points towards the staging buffer.
