Description T 2016-07-08 18:09:37 UTC
Description of problem:

On fully up to date Fedora 24 with KDE/kf5 and Intel HD graphics 530 I have display artifacts from closed windows and in particular Emacs X11 is unusable since it does not redraw on any input or buffer change without window resizing or an explicit M-x redraw-display.

Version-Release number of selected component (if applicable):



# lspci -v -s 00:02
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06) (prog-if 00 [VGA controller])
        Subsystem: ASUSTeK Computer Inc. Device 8694
        Flags: bus master, fast devsel, latency 0, IRQ 136
        Memory at de000000 (64-bit, non-prefetchable) [size=16M]
        Memory at c0000000 (64-bit, prefetchable) [size=256M]

        Capabilities: [200] Address Translation Service (ATS)
        Capabilities: [300] Page Request Interface (PRI)
        Kernel driver in use: i915
        Kernel modules: i915

How reproducible:


Steps to Reproduce:
1. start emacs 
2. make modifications in a buffer
3. text is not refreshed becomes garbled
4. M-x redraw-display is necessary after any buffer activity


1. open firefox
2. watch embedded video on google-news
3. close the embedded video
4. outline of the video window remains as a transparent blue rectangle


Expected results:

emacs should work normally
closed windows should not leave behind shadows of themselves

Additional info:

I did not have these issues with Fedora 23 on the same machine.
I determined that the difference between F23 and F24 was that the intel driver in F24 is using glamoregl

/var/log/Xorg.0.log.old:[    20.359] (II) Loading sub module "glamoregl"
/var/log/Xorg.0.log.old:[    20.359] (II) LoadModule: "glamoregl"
/var/log/Xorg.0.log.old:[    20.359] (II) Loading /usr/lib64/xorg/modules/
/var/log/Xorg.0.log.old:[    20.368] (II) Module glamoregl: vendor="X.Org Foundation"
/var/log/Xorg.0.log.old:[    20.368] (II) glamor: OpenGL accelerated driver based.
/var/log/Xorg.0.log.old:[    20.385] (II) glamor: EGL version 1.4 (DRI2):
/var/log/Xorg.0.log.old:[    20.392] (II) modeset(0): glamor initialized

while F23 was using SNA. 

I solved this problem by compiling xf86-video-intel (git HEAD  26f8ab5) myself and using SNA 

> grep -i sna /var/log/Xorg.*
/var/log/Xorg.0.log:[ 20248.547] (II) intel(0): SNA compiled from 2.99.917-676-g26f8ab5
/var/log/Xorg.0.log:[ 20248.549] (II) intel(0): SNA initialized with Skylake (gen9) backend
/var/log/Xorg.9.log:[    24.401] (II) intel(0): SNA initialized with generic backend

With the SNA driver everything works ok.

today's update from Fedora

# rpm -qi xorg-x11-drv-intel-2.99.917-24.20160712.fc24.x86_64
Name        : xorg-x11-drv-intel
Version     : 2.99.917
Release     : 24.20160712.fc24
Architecture: x86_64
Install Date: Wed 27 Jul 2016 05:47:19 PM MDT

solves the emacs redraw issue for me. The driver now works out of the box with no special settings required. There still is the lingering blue rectangle from any video embedded in a browser, though.

Comment 2 Fedora End Of Life 2017-07-25 21:41:10 UTC
This message is a reminder that Fedora 24 is nearing its end of life.
Approximately 2 (two) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 24. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '24'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 24 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Comment 3 Fedora End Of Life 2017-08-08 15:27:50 UTC
Fedora 24 changed to end-of-life (EOL) status on 2017-08-08. Fedora 24 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this

Thank you for reporting this bug and we are sorry it could not be fixed.
