[Pkg-xfce-devel] Bug#811290: xfwm4: Visible line on screen that changes with window manager theme

[Kyle Bentley]

Package: xfwm4
Version: 4.12.3-1
Severity: important

Last night I upgraded my notebook from Jessie to testing, for testing purposes. \
It's hard to describe, but there is a grey border that runs across the screen, and it \
appears to be a window border of some kind.  In the xfce settings, under the window manager \
options, I can change the theme from default to any of the others, and this border changes \
to reflect the selected theme. Without measuring, it appears about 4/5 of the way down the screen. \
This wasn't a problem in Jessie, and I was using kernel 4.3 from backports then, and using the \
default testing kernel 4.3 now.  So I do not think it's a problem with the kernel.  The fact that \ 
I can manipulate the border in the xfce window manager settings is what makes me thing this is \
a relevant bug.  It also does not appear in the BIOS, or grub menu, so it cannot be hardware \
related.

The hardware is a Lenovo T550, using the Broadwell i7 5600U processor + graphics.
