[Bug 1575000] Re: font glyph corruption on dialog box

[NoBugs!]

Also affects 14.04 where I kept getting missing letters, or missing
icons when using latest 4.4 kernel. It didn't happen earlier so I
downgraded to 4.2-lts wily kernel. And yes I checked the memory was not
faulty.

There's been quite a bit of talk about the Linux 4.4 version having a
bug with Intel driver with graphics corruption or missing letters on the
screen:

[Timo Aaltonen]

it's not a libreoffice bug but xserver, yakkety has 1.18.4 which
includes the fix

xenial-proposed has it too, just forgot to add the buglink to this one,
so please test that package

[Bug 1575000] Re: font glyph corruption on dialog box

[Yuri Ribeiro Sucupira]

Enabling OpenGL rendering also solved this for me (the attached file
shows which checkbox must be enabled/marked/checked, at the LibreOffice
GUI).

I'm running LibreOffice 5.1.4.2 on a 64-bit XUbuntu 16.04 "Xenial Xerus"
system. My computer is a Dell laptop (Dell Inspiron 5548) which has
hybrid graphics (it has two GPU - Graphics Processing Units): GPU 1 is
an Intel Broadwell-U Integrated Graphics (it's embedded into the i7
CPU/processor), while GPU 2 is an Advanced Micro Devices [AMD/ATI] Topaz
XT [Radeon R7 M260/M265] (it's a PCI Express 3.0 graphics card).

*Ubuntu (Ubuntu, XUbuntu, KUbuntu...) 16.04 distros ship with kernel
4.4.X, which has a bug that causes malfunction of the kernel with the
open source "amdgpu" and "radeon" graphics drivers (they superseded the
proprietary "fglrx" driver by AMD). See bug #1608042
(https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-
amdgpu/+bug/1608042).

Hence, if your computer has any AMD GPU (despite of your computer having
hybrid graphics or not), and if your distro is *Ubuntu 16.04 and you
already installed MESA (OpenGL support for Linux) and activated OpenGL
rendering in LibreOffice, but the issue remais, it is likely that your
system is affected by the kernel/AMD bug.

It's thus recommended to download and install a further stable kernel,
like e.g. kernel v4.7.2:

- For 64-bit *Ubuntu, download these three files:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.2/linux-headers-4.7.2-040702_4.7.2-040702.201608201334_all.deb
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.2/linux-headers-4.7.2-040702-generic_4.7.2-040702.201608201334_amd64.deb
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.2/linux-image-4.7.2-040702-generic_4.7.2-040702.201608201334_amd64.deb

- For 32-bit *Ubuntu, download these three files:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.2/linux-headers-4.7.2-040702_4.7.2-040702.201608201334_all.deb
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.2/linux-headers-4.7.2-040702-generic_4.7.2-040702.201608201334_i386.deb
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.2/linux-image-4.7.2-040702-generic_4.7.2-040702.201608201334_i386.deb

...then open a shell terminal window, cd (change directory) into the
folder where you donwloaded those DEB packages into, then install the
packages and restart your system. For instance, if you downloaded those
DEB packages into your downloads folder (/home/your-username/Downloads),
then this command will cd into your downloads folder, install the
downloaded packages and restart your system (your password will be asked
by the shell):

cd ~/Downloads ; sudo dpkg -i linux-*.deb ; telinit 6

Turning OpenGL fixed the garbled text but my computer completely froze
two times so I had to turn it off again.

[Bug 1575000] Re: font glyph corruption on dialog box

[Bryan Quigley]

Here is a debdiff for yakkety.

I've tested the binary produced for xenial (previous and pretty much
identical debdiff) and it fixes the issue on my hardware.  I don't have
hardware to test this on yakkety though (live sessions don't work well
on the hardware).

[Bug 1575000] Re: font glyph corruption on dialog box

[Stéphane Berthelot]

I suffer from the same problem with current updated libreoffice 5.1.4 on "Cape 
Verde PRO [Radeon HD 7750/8740 / R7 250E"
I cannot easily recompile glamor on this box but can someone test the attached 
patch from this freedesktop report and see if it fixes the problem ?

[Bug 1575000] Re: font glyph corruption on dialog box

[Vertago1]

I just tested the 5.2.0.0 debs from: 
http://ftp.utexas.edu/libreoffice/libreoffice/testing/5.2.0/deb/x86_64/LibreOfficeDev_5.2.0.0.alpha1_Linux_x86-64_deb.tar.gz
and they do not show the problem.

This is still a problem for the version of libreoffice available in
ubuntu 16.04 and should be addressed. Currently, the only demonstrated
work-around is to install a prerelease version of libreoffice not
available in the repositories.

I don't understand. It is being marked as invalid because Libreoffice
Version 5.1.2.2 shows the problem but 5.2.0.0.alpha1 doesn't?

I also get finally the complete freeze as znmeb-o, not immediately but
after using LibreOffice for a while. So forget about my workaround.

screencast

Running the open-source "radeon" gallium X.org drivers with a Radeon HD
7770 (radeonsi chipset) on Fedora 23 64-bit, with LibreOffice 5.1.1.x
and 5.1.2.x downloaded from the LibreOffice website, some of the
LibreOffice dialogs show broken text glyphs. See attached screencast.

This is with experimental features turned off, and the traditional UI
backend (not the GTK3 one). Couldn't find a way to try out the GTK3
version from the RPMs downloaded from the LibreOffice website (even if I
check "Enable experimental features")

So far I observed this problem only in LibreOffice, no other software.

The issue disappears when OpenGL is switched on.

The workaround in #5 works for me, my settings are in the description of
the bug. If you want to provide more information, I think it is best in
the two upstream bug reports linked to this one.

[Bug 1575000] Re: font glyph corruption on dialog box

[M. Edward (Ed) Borasky]

The workaround is worse than the symptom! I have Ubuntu GNOME 16.04 with
[AMD/ATI] Bonaire XT [Radeon HD 7790/8770 / R7 360 / R9 260/360 OEM].
I'm running the low-latency kernel, if it matters: 4.4.0-21-lowlatency
#37-Ubuntu

I went into the menu as described, restarted LibreOffice Calc and opened
the spreadsheet. Instead of garbled test, the dialog box was completely
blank. Then ... the screen went totally dark and Ctl-Alt-Delete no
longer worked. I ended up doing a hardware reset.

Are there by any chance some log files I can attach, or do you already
know what this is?

The workaround in #5 didn't work for me. I tried checking "Force OpenGL
even if blacklisted (on restart)" and it is still showing: "Current GL
status: Disabled" I am running Kubuntu 16.04 though, so it might work
for Ubuntu.

A workaround. Open the Tools -> Options -> View menu, and mark "Use
OpenGL for all rendering (on restart)", restart LibreOffice.
