Bruno Nova, in order to allow additional upstream developers to examine the
issue, at your earliest convenience, could you please test the latest upstream
kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ?
Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the
daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was
released upstream.
4) Install instructions are available at
https://wiki.ubuntu.com/Kernel/MainlineBuilds .
If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.
If the latest kernel did not allow you to test to the issue (ex. you couldn't
boot into the OS) please make a comment in your report about this, and continue
to test the next most recent kernel version until you can test to the issue.
Once you've tested the upstream kernel, please comment on which kernel version
specifically you tested. If this issue is fixed in the mainline kernel, please
add the following tags by clicking on the yellow circle with a black pencil
icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ
Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.
If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ
Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.
Also, you don't need to apport-collect further unless specifically
requested to do so.
It is most helpful that after testing of the latest upstream kernel is
complete, you mark this report Status Confirmed.
Lastly, to keep this issue relevant to upstream, please continue to test
the latest mainline kernel as it becomes available.
Thank you for your help.

Title:
Sometimes a black rectangle appears briefly under the mouse cursor
Status in xorg-server package in Ubuntu:
Incomplete
Bug description:
I'm on 16.04, using a laptop with Nvidia Optimus (Nvidia driver installed,
Intel card selected).
The problem also occurs in a guest session.
It didn't occur in 14.04.
Sometimes I see a black rectangle appear for a very brief moment (a flash).
Horizontally, the rectangle occupies the whole screen.
Vertically, the rectangle seems to start in the mouse cursor and ends in the
bottom of the screen.
The easiest way to reproduce the bug is to open a Gnome terminal, move
the mouse cursor inside the window and press Alt+Backspace repeatedly.
WORKAROUND: Switch to the nvidia card.
