Created attachment 82656 [details] example of corruption After the last update to 2.21.12-12-g6c8b15d I started seeing random image corruption on screen like vertical or horizontal lines. See the picture for illustration, there are two of the corruptions.
Created attachment 82657 [details] xorg.log
Created attachment 82658 [details] another example
Do you know which commit you used last? Looks like a dup of bug 67015 or bug 67045, both of which I am unsure about yet.

I'm not sure about 884dd896e4e959e5a284a6f70da9e5cde1bbb7e9... It's not so easily reproducible to test :/.
I haven't noticed anything that is described in the two bugs above.
In the meantime I also updated the kernel from 3.9 to 3.10. So it might be relevant too.
Essentially, you are doing your daily tasks under KDE until corruption shows up and spoils the party? Is the corruption gradual, or spontaneous? Is it transient?

What can be seen on the first image is spontaneous, I do not see it anywhere now. But since I saw what is on picture 2, I see now those thick lines on most my window decorations.
Could be the fence bug, at least if you've throw in a resume once a while. See https://patchwork.kernel.org/patch/2828671/
Also 3.10.1 doesn't have the read-read/read-write fixes yet, which could be related.
Created attachment 82704 [details] another artifact (In reply to comment #10) > Could be the fence bug, at least if you've throw in a resume once a while. > See > > https://patchwork.kernel.org/patch/2828671/ I built a 3.10.1 kernel with that patch, but this one on its own does not help entirely. I still see the artifact attached. It should be the psi's star, the orange star at http://psi-im.org/. Nothing more than that happened yet.

(In reply to comment #13) > commit daa13e1ca587bc773c1aae415ed1af6554117bd4 Those 3 and 2.21.12-29-g65a0943 and I am still seeing what is depicted in attachment 82704 [details]. I haven't seen the previous corruptions yet. Maybe this is a different bug? For me it looks like it appeared with one of the updates in the past few days...
I think I have that systray corruption resolved: commit 2c78403cb56841f342692b97bb53e995c3ff6b9f Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sat Jul 20 21:55:16 2013 +0100 sna: Remember to apply drawable offsets for composite memcpy Yet another missing chunk from commit 6921abd81017c9ed7f3b2413784068fbc609a0ea Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Jul 18 16:21:27 2013 +0100 sna: Add a fast path for the most common fallback for CPU-CPU blits I had the composite offsets, but not the normal window offsets!
