Bug ID: 473819
Summary: Environment becomes "glitchy" when monitors are awoken
from sleep
Classification: Plasma
Product: plasmashell
Version: 5.27.7
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: entangled_mousiness...@flamingohippo.com
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
SUMMARY
When returning to my computer and the (two) monitors are awoken from sleep, the
desktop environment glitches out.
STEPS TO REPRODUCE
1. Be inactive from computer until monitors goes to sleep by the "Screen Energy
Saving" option
2. Wake up the monitors and login
3. Monitors are broken.
OBSERVED RESULT
The wallpaper on the primary monitor becomes black and gets the "ghosting"
effect when you drag around windows and move the mouse. Like the infamous
behavior on older Windows versions.
The wallpaper on the secondary monitor also becomes black, but this ghosting
effect isn't here on this one.
The KDE taskbar kind of disappears but pressing the Super-button works to open
applications and already opened applications seem to work.
EXPECTED RESULT
The desktop should look and behave normally like from a fresh boot after the
monitors comes back to sleep.
SOFTWARE/OS VERSIONS
Linux: Fedora Linux 38
KDE Plasma Version: 5.27.7
KDE Frameworks Version: 5.109.0
Qt Version: 5.15.10
ADDITIONAL INFORMATION
I just installed Fedora 38 KDE today, so the installation is fresh. Barely
gotten to install anything yet.
I've also installed NVIDIA drivers for my GTX 980 from rpmfusion:
https://rpmfusion.org/Howto/NVIDIA
> $ modinfo -F version nvidia
> 535.98
The behavior and experience is similar to the one I had around the beginning of
the year when I used Kubuntu with a dual-monitor setup. Something about the
handling of monitors had to be rewritten to my understanding and the fix was
shipped in KDE 5.26/5.27, which was part of Kubuntu 23.04. After that release I
had no problems there.
