If I put my computer in sleep/hibernate (doesn't seem to matter which one) the screen gets corrupted with colors everywhere. It does update, and things jump around when I try to press buttons, bring out menus, etc. It's like the drawing buffer is all jumbled up and it's reading/writing from/to the wrong place.
When something is updated, it's like I can see the picture/pixmap/icon for a fraction of a second, but then it's corrupted again.
If I move the mouse continuously over a menu, to update the highlighting of it, I can see at least where I am on the screen. But the fonts are complete garbage, and it's unreadable. Perhaps I can photograph the screen if it's needed. I haven't tried taking a screenshot.
I'm using Gentoo, 3.11 gentoo-kernel, with Systemd and Gnome 3.8.
The TTY:s are not corrupted, so I'm able to switch to a TTY without problems.
I'm using a green background, and the whole corrupted screen is green. The screen looks like big green chunks that flickers when it's updated as I move the mouse.
You mean when you wake up from suspend/hibernate so see the corruption? Please attach your xorg log and dmesg output.
Also is this a regression? If so, can you bisect?

Xorg log including sleep and wakeup cycle, as well as shutting down afterwards.
Yes exactly, the corruption occurs when the computer wakes up from sleep/hibernation.
The behavior started at least two kernel versions ago, probably at 3.10. I _think_ it was working with 3.8, but I will check that soon, and get back to you.
Here's the Xorg.0.log.old from previous run. I was running for a while, and then put the computer in sleep mode, and then awoke it immediately. When the corruption has occurred, I shut it down normally.

dmesg, including hibernate cycle
Here's my dmesg output from last boot, including hibernation. The hibernation does not seem to work for some reason, because the computer wakes up immediately, but the screen still gets corrupted.
The screen gets corrupted on kernel 3.8.5 (which is the oldest kernel I have lying around) as well. I'm typing this blindly.
I don't know if I can bisect... I need some help in that case.
Gentoo has recently added a dependency on Systemd as a part of Gnome 3.8, and I think recovering from sleep/hibernate was working before that. But I'm not completely sure. Without systemd, sleep/hibernate doesn't work at all, so I'm unable to revert and test without it.
Here's a link to a video showing the problem. https://www.youtube.com/watch?v=t3RBRwMxrsk
Make sure you kernel has this patch:
Yes, the patch seems to be in 3.11.1, as well as 3.11.0. I'm currently running:
$ uname -a
Linux skare 3.11.1-gentoo #1 SMP PREEMPT Thu Sep 19 15:18:53 CEST 2013 x86_64 Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz GenuineIntel GNU/Linux
Is there any debugging information/logging I can turn on during boot, and test again for more information?
Ideally you could bisect.
I haven't been able to disect anything yet, but I do have some updated information. I switched back my BIOS settings to Hibernate via S3 instead of S1 (which I was forced to switch to because of Windows 7 somehow disabling my hibernate possibility because of some "known issue with power management" or something like it) and now my glitches are gone! The hibernate and wake-up works perfectly. I have yet to try Sleep I think, but I think I tried and it doesn't work at all since my motherboard only supports _either_ S1 or S3.
This is very strange though, since I'm fairly certain I've used both of them before.
