Bug ID: 466429
Summary: Slideshow wallpaper stuck in transition between two
images after the monitor is awakened
Classification: Plasma
Product: plasmashell
Version: 5.27.1
Platform: openSUSE
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: Image Wallpaper
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Target Milestone: 1.0
SUMMARY
***
I have my wallpaper set as a slideshow that changes the image every few
minutes. When I leave my computer for some time, the monitor turns off for
energy saving. Later, when I wake it up, the background seems to be an image
that got stuck in the middle of a transition between two wallpapers (i.e.
ghosted). That is, both images are blended together.
This happens every time I leave my computer for long enough and find my screen
turned off when I'm back, It's been happening for years, but never got around
to reporting it, because it's not a severe thing, just an annoyance. However,
it leaves Plasma in a bad place any time I come to my computer with somebody
and the first thing they see is a broken wallpaper!
***
The short times proposed below are not necessary at all to reproduce the bug,
just to reproduce it faster.
STEPS TO REPRODUCE
1. Set a slideshow wallpaper with a transition time of 1 minute.
2. Go to the energy saving settings and configure your screen to turn off after
two minutes.
3. Wait for the screen to turn off. Then wait a couple of minutes more, to
ensure that the wallpaper presentation attempts to do more transitions
underneath (at least that's what I guess it's happening).
4. Wake up your screen.
OBSERVED RESULT
The background is basically two wallpapers blended together.
EXPECTED RESULT
Just one of the wallpapers of the slideshow.
