I tested a few more kernels.
The bug is also fixed in v4.6-rc1.
Don't know about earlier kernels.

I had an old hard drive around, so I installed Ubuntu to it.
I installed the latest kernel from that link (v4.8-rc5), and the bug is fixed
there.
I haven't installed the NVidia proprietary drivers.

Yes, after removing the nvidia proprietary driver and replacing it with
nouveau I can still reproduce the issue.

Sure Christopher!
A screencast couldn't record the graphical glitches, so I recorded a
video with my phone and attached it to this comment.
In the video I have gnome-terminal open.
At the start, I press and hold the 'A' key on the keyboard and move the
mouse cursor *inside* the terminal window.
I now switched to the NVidia card, and I couldn't reproduce the bug.
So this may be specific to Intel.

Even more interesting...
I'm developing a small game in SDL.
It runs in a window, hides the cursor, and in every frame moves the cursor to
the center of the window.
But if I move the mouse fast enough for the cursor to exit the window, it is
shown for a split second and, more importantly, that b
I just purged the bumblebee packages and installed nvidia-prime.
I wasn't using the NVIDIA card anyway, so I didn't need dynamic card switching
(except to work around a defect in my laptop, but I already found another
workaround).
Still, the update shouldn't have broken bumblebee (even if it isn'
The recent upgrade to nvidia-340 in Trusty broke bumblebee. After plymouth, it
goes to a black screen.
The version in the Bumblebee's PPA is also not perfect. It works, but after
running optirun/primusrun, the GPU stays ON because it fails to unload the
nvidia module.

Ok, you're right.
I thought that /usr/lib/nvidia-331-prime/ld.so.conf was used only for 64-bit,
but it is indeed used for 32-bit as well.
Same thing for /usr/lib/nvidia-331-prime/ld.so.conf, which point to both 64 and
32 bit mesa libraries.
As I said, you know more about this than me. :)

@Alberto, sorry to confuse you.
I am using Bumblebee, but I have everything working now. The alternatives are
pointing to the Mesa GL libraries, nvidia-331 installed and
libgl1-mesa-glx:i386 installed (though it's not installed by default nor by
bumblebee, so I reported Bug #1383909 there).

@Alberto Milone, sorry to bother you, could you check this bug?
I was trying to understand why the NVIDIA driver package installs an empty
alt_ld.so.conf file.
Then I found the commit that added this change by you in Oneiric:

The default GL option for x86_64 is mesa because bumblebee selects it during
install, using update-alternatives.
But, for some reason, it doesn't do the same for i386.

I've tested this a bit more.
The issue is a lot more serious than I thought!
The workaround provided by the bug reporter probably works for computers
using an NVIDIA card. And my fix would probably work too.
However, for computers with Hybrid graphics/NVIDIA Optimus (Intel+NDIVIA), like

I've looked at the source code of nvidia-graphics-drivers.

Sure, I could file another Xorg bug.
But, like I said (maybe not clearly), I don't think this is a Xorg issue at all.
The problem is in Unity, I think.
