I can confirm the same issue on a Dell Latitude E4300 with Intel GMA X4500HD graphics.

My machine is usually in a docking station with 2 x DVI outputs running 2 x 1920x1080 monitors, and similarly to James I see the issue after usually some uptime, have seen the issue for the past few weeks, and restarting fixes the issue for a while.

I'm running Gnome Shell and restarting it or the X server doesn't help.

Text corruption/missing text

Same effect observed on an Lenovo T410s, when using an external monitor, using "duplicate display" mode of operation.  Extremely frustrating.

Same problem with a Dell Latitude E5400 Laptop and an Intel Integrated Graphics card.

I can confirm this happens also Lenovo T510 model on dual external monitors.

This happens for me with a Lenovo T510, on docking station with one external DVI monitor.  Laptop lid is closed, so the external display is the only active screen.

I haven't noticed this behavior when using the laptop undocked and disconnected from external displays, but I can't be 100% sure it doesn't happen in that configuration.  I don't go undocked very often or for prolonged periods of time.

Hi!

Same problem as described by the other users - on a Lenovo X201s with external 1920x1090 monitor. Connected via dockingstation display port (displayport->dvi adapter).

I have the graphics problems on both displays. Although in some cases moving the application (e.g. Thunderbird) from the big monitor to the laptop display fixed the problem.

I also have this problem, it started about the same time as the first 3.5 kernel came out.  I have the Lenova T510 (intel graphics, same lspci post as the OP)

Kernel: Linux oz3 3.5.4-1.fc17.x86_64 #1 SMP Mon Sep 17 15:03:59 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
X driver: xorg-x11-drv-intel-2.20.8-1.fc17.x86_64

Also on T510. Using two monitors (external displayport and laptop panel) with a single X screen. It has to do with the kernel version. 3.4.4-5.fc17.i686.PAE works for me. Everything I've updated to after that (including latest, I updated and rebooted this morning) does not work for me: a little while after starting to use the desktop, text starts failing to repaint. It gets worse over time - at first it works, but text fails to render more and more often until things are completely unusable.
The laptop has an nvidia chip in it too, but it's disabled in BIOS; just using the intel.

I also have this issue on my T510, docked and with external monitor connected. I am using

Any updates on this issue? These rendering issues are really disturbing. A workaround would be very appreciated.

Martin, downgrading to kernel 3.4.4-5 works around it for me. (Fortunately, since the computer is not usable with this bug.)

guys duplicate, please test the scratch kernel if its still around, trying to get intel to work it out.

Thanks Havoc for this suggestion, this is what I did on my box. I will stick with 3.4.* kernels until this bug is resolved as it can be really annoying.
