Dear Maintainer,

Screen tearing while moving windows or while watching video seems to follow
XFCE in all latest versions.

Seems to work just fine for me.

I can confirm that in three different machines (two laptop and one
desktop) with different graphic cards (nVidia and Intel), this problem
still exists.

Yes. Your best bet is to reopen the bug as I have done, and provide
additional information so that someone else can reproduce the issue.

Specifically, the video drivers, video cards, layouts, and possibly even
screenshots/pictures of the tearing would all be required in order to
make any progress.

In this screenshot you can see clear how screen tearing occurs on fast
frame changes and how horizontal lines split screen in pieces.
It is taken from a fresh install of debian testing rc2 amd64 system on
my acer 3810tz.

The screen tearing is in the video player. It looks pretty much
unrelated to Xfce.

Of course is in the player because the screenshot was on the window and
not the hole screen.
Also the screen tearing occurs  on moving items, that's why you can see
it on frames or when you move a window such us the thunar file manager
on previous screenshot. Take a look what happen when i move the player
around (Any player or window). This is tested with both enable/disable
compositing in settings. Also when doing the same thing with GNOME, KDE
or MATE, this doesn't happen.

This is a fresh install from the official latest stable release debian
8.1 (jessie) 32 bit installer with xfce 4.10 on a toshiba satellite A100
with Intel Mobile 945GM/GMS/GME 943/940GML Express Integrated Graphics
Controller rev 03.
And exactly the same happens with testing (xfce 4.12) on the same machine.
