Package: src:linux
Version: 4.8.11-1~bpo8+1
Severity: important
Dear Maintainer,
Screen corruption was randomly (but consistently) observed on several
programs: LibreOffice 5, xpdf, iSilo under wine.
I do not know which precise piece of the software stack is causing this
error, but I want to start from the kernel-level driver, since I noticed
the problem for the first time when I upgraded my kernel version
from 4.3 to 4.6.
The problem was observed also on the newer kernel releases (4.7, 4.8).
And I tested today, and found that some of the problems also appeared
using the old kernel 4.3.
This is a problem that I began to observe since July 2016, when I upgraded
the backport kernel in my computer to version 4.6 onward, and the
xserver-xorg-video-intel driver to version 2.99.917+git20160522-1~bpo8+1 .
Some of these problems happen consistently; the others happen somewhat
intermittently, but frequently enough to be annoying.
This problem happens on the following hardware platform:
* Lenovo Thinkpad T450s
* CPU: Intel i5-5200U (Broadwell)
* OS: Debian 8 (Jessie) 64-bit
* Kernel versions affected: 4.3, 4.6, 4.7, 4.8 as provided by
"jessie-backports" repository
* Xorg driver: intel with "sna" acceleration.
I used the newest Intel driver software provided by jessie-backports,
since the official release (kernel 3.16) have a lot of issues with
Broadwell hardware.
* Kernel command line: (UUID erased)
BOOT_IMAGE=/boot/vmlinuz-4.3.0-0.bpo.1-amd64 root=UUID=xxxxxxxxxxx ro
intel_iommu=igfx_off
Additional comments:
* This corruption was observed on both the physical screen, as well as
the virtual screen when viewed via x11vnc.
* I tried "modesetting" X11 DDX to replace the "intel" driver.
It came with its own set of problems, see
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=835123
I am a long-time user of Linux/GNU systems, but I am not a Linux kernel
expert. If you need me to gather some information from my running system,
I should be able to help.
Here are some account of the real cases:
========================================
LibreOffice 5 (concretely: 5.2; other versions could be affected too)
---------------------------------------------------------------------
I noticed the following actions were conducive to triggering the bug:
1) editing a spreadsheet cell that already has a content
2) editing text document
3) page up/page down in a text document
4) pasting a moderate length of a paragraph onto a text document (say,
the length of the paragraph is about half a screen's height)
Here is an example of a consistent problem.
Easy step to reproduce bug in the worksheet in LibreOffice 5.2:
* Open this sample document: "Video-training-sheet.ods"
* Go to the cell B29 with content:
"Lord's table on 1/15 and 1/22 will begin at 9:30am"
* Press F2
* Move the cursor to somewhere in the middle, say to the beginning of the
word "will"
* insert some text -- then the text to the right of the cursor will be
corrupted because of overwriting of old pixels with new pixels without
erasing the old ones.
I did several tests with other version of LibreOffice, as well as a
different host. Here is the summary table:
Hostname Host OS metal? software Corruption?
compsci-wp Linux 3.16 docker LO-5.2.4 official build No
wirawan2 Linux 4.3 docker LO-5.2.4 official build Yes
wirawan2 Linux 4.3 docker LO-4.3.3 debian official No
wirawan2 Linux 4.7 direct LO-5.2.4 debian backports Yes
"Corruption" refers to whether the screen corruption occured when I edited
the sample document "Video-training-sheet.ods" above.
Xpdf
----
Please view the enclosed file, "sunway-report-2016.pdf", which
can be downloaded from:
http://www.netlib.org/utk/people/JackDongarra/PAPERS/sunway-report-2016.pdf
(md5:f8bf0f6f7859987714d1df66de016e6c).
On page 8, as the picture was being composed, the top left corner of
the document blinks with with "animating" images until that picture is
fully composed.
This problem occurs with Kernel backport version 4.3 and 4.8.
The following problem (the picture shown as xpdf-screen-5.png) seems to
only occur on newer kernels (4.6, 4.7, 4.8):
When one nagivates with Page-Up and Page-Down keys, at some (seemingly)
random moments, the displayed picture was corrupt.
See that attached picture file.
iSilo under Wine
----------------
This is a more complex setup. It is a 32-bit wine running under Docker
container (with 32-bit Ubuntu-14 base image), which is used to run
Windows version of "iSilo" software (a electronic document reader).
Other than the iSilo itself, I used software provided by Ubuntu
14.04.3 repository.
Often the document is drawn with corruption, see file isilo-screen-1.png .
(Attachments will be included in a subsequent email.)
In summary: I think this is an important problem to address, as I have
been having a lot of pains with graphics issues on this Intel Broadwell
hardware. I seem to not be able to find the right configuration that
allows Linux OS to run "out of the box" with this 2-year-old hardware
platform. I am surprised that nobody reported this problem earlier (at
least not to my knowledge).
Thanks,
Wirawan
