Bug ID: 405724
Summary: multi-screen to single screen slideshow memory leak
Product: plasmashell
Version: 5.15.2
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: Image Wallpaper
Assignee: notm...@gmail.com
Reporter: rtver...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
SUMMARY
This is on a laptop hooked up to multiple monitors via docking station (laptop
is closed & screen is off).
After the last slideshow memory leak, I didn't start using slideshow again
until recently. I had a running session for nearly two weeks with reasonable
plasmashell memory usage - it started at about 90mb after a fresh boot,
gradually rose to around 200mb, then hovered +/- from there.
I then used the laptop disconnected from the docking station, using the
laptop's screen. plasmashell memory usage rapidly rose to around 1.4gb during
the roughly 8 hours that the laptop was on; though I was not at the laptop, it
was mostly sitting on a desk idle.
I then docked the laptop again (lid closed, laptop screen off), and memory
usage has continued to rise in the roughly 1 hour that I've been using it back
on the dock to a little over 1.5gb.
STEPS TO REPRODUCE
1. configure slideshow, rapid shuffle time to exacerbate memory leak.
2. start new session with a screen turned off, but some other screens on. (ie,
laptop screen off, desktop monitors on).
3. watch memory usage level off at reasonable usage.
4. swap screens (ie, turn on the ones that were off at #2 above, and turn off
the ones that were on)
5. watch memory usage rise dramatically.
OBSERVED RESULT
plasmashell eats too much memory.
EXPECTED RESULT
plasmashell maintains balanced diet.
