Bug ID: 480815
Summary: kwin_x11 spams my system log whenever my screen goes
to sleep with a warning about my icc profile
Classification: Plasma
Product: kwin
Version: 5.93.0
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: platform-x11-standalone
Assignee: kwin-bugs-n...@kde.org
Reporter: adam.m.fontenot+...@gmail.com
Target Milestone: ---
SUMMARY
I've been using the X11 session for the last few hours because I'm trying to
solve a different bug. Almost as soon as I did so, I noticed the first time my
screen went to sleep that my laptop's fan went crazy and it started heating up
significantly.
Since then I've been trying to work out the cause, and it appears to be KWin
trying and failing to do something repeatedly with the screen (or screens) that
aren't on. Since I've been working on the problem, my screen has been off for
only brief intervals for testing, and yet in only 3 hours the following has
been printed to my system log 11,183,200 (!) times:
kwin_x11[24922]: qt.gui.icc: fromIccProfile: failed size sanity 2
STEPS TO REPRODUCE
Note that I haven't confirmed that all these steps are necessary for
reproducing the issue.
1. Use the Plasma X11 session.
2. Have an external screen attached and Plasma set to display only on the
external screen. The laptop lid is closed.
3. Have an ICC color profile that you've made for the screen with DisplayCal
set for the screen in colord.
4. Allow the screen to turn off automatically.
OBSERVED RESULT
The log is spammed with the message shown above, system activity increases -
I'm not sure yet whether the log spam is a symptom of the system problem, or if
the system problem is a symptom of the log spam.
EXPECTED RESULT
No log spam, laptop stays cool, fans stay silent.
