Description Peter Backes 2017-06-10 12:35:13 EDT
Description of problem:
When I start parole, cpu goes to 100%, and key repeat no longer works. strace parole shows that it's continuously reading and sending data over the X socket.

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

How reproducible:

Steps to Reproduce:
1. parole
2. top
3. go to some text input field (any, may be a different program), press key and keep it pressed

Actual results:
key repeat does not work, or only sporadially
cpu goes to 100%, partly used by parole, partly used by X

Expected results:
key repeat works fine
cpu stays low

Additional info:
if I open and start some video in parole, the misbehaviour stops after a small delay
Comment 1 Peter Backes 2017-06-10 12:47:57 EDT
Note that I installed I upgraded to parole-0.8.1-3.fc26.i686 for testing purposes. When I downgrade again to parole-0.8.1-2.fc24.i686 (current version in the f25 repo), things are the same.

The behaviour seems to be related to whether the parole window has focus. If it has focus, parole runs at around 10% cpu (still a lot). If it loses focus, the effect occurs. When the effect goes away after playing some video, and parole gets focus and loses it again, the effect re-occurs.
Comment 2 Fedora End Of Life 2017-11-16 13:52:07 EST
This message is a reminder that Fedora 25 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 25. 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bug reports from releases that are no longer maintained.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 '25'.

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 25 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 Peter Backes 2017-11-16 18:09:29 EST
Still reproducible on f26
