Description David Howells 2016-10-18 21:17:44 UTC

Description of problem:

I'm seeing an issue where the contents of a window suddenly stop being updated except instantaneously at the point where the window is switched away from or switched back to. I'm seeing this on two different computers with different h/w, different DE's and different applications:

(1) An x86_64 PC with a NVIDIA Corporation GF106 [GeForce GTS 450] (rev a1) graphics card running KDE. This happens with konsole, xterm and emacs there.

(2) An Intel i3 NUC box with Intel Corporation HD Graphics 5500 running Gnome. I've only seen this there with mythfrontend, but that and skype are all that normally run there. With mythfrontend, this seems reliably caused by playing a video. After the video completes, the normal interface is only redrawn if I flip to another app. However, I can navigate blind to another video and play that and the video playback is fine.

With konsole, xterm and emacs, this has been happening for a while and definitely goes back a few Fedora iterations. For mythfrontend, this started happening with the upgrade to F24.

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

Computer (1):

kernel-4.7.5-200.fc24.x86_64
xorg-x11-server-Xorg-1.18.4-4.fc24.x86_64
mesa-libEGL-12.0.3-1.fc24.x86_64
konsole5-16.08.1-2.fc24.x86_64
kwin-5.7.5-1.fc24.x86_64

GNU Emacs 25.1.50.1 (compiled by me, not using libXaw3d not gtk).

Computer (2):

kernel-4.7.6-200.fc24.x86_64
xorg-x11-server-Xorg-1.18.4-4.fc24.x86_64
mesa-libEGL-12.0.3-1.fc24.x86_64
mythtv-frontend-0.28-7.fc24.x86_64
gnome-shell-3.20.4-1.fc24.x86_64

How reproducible:

With mythtv-frontend - 100%.

Steps to Reproduce:
1. Start emacs/konsole/whatever.
2. Use it for some amount of time till the problem happens (might be days of constant use, might be minutes, might not seem to happen at all).

or:

1. Start mythfrontend.
2. Navigate to the recorded videos.
3. Play video to completion.
4. The screen goes black with just a mouse cursor on it.
5. Switching to a running gnome-terminal will cause a redraw.

Comment 1 Fedora End Of Life 2017-07-25 23:32:07 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bug reports from releases that are no longer maintained.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 2 Fedora End Of Life 2017-08-08 19:28:51 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
bug.

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