Bug ID: 455812
Summary: "Use accent color from current wallpaper" behaves
improperly with slideshows
Product: systemsettings
Version: 5.25.0
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: kcm_colors
Assignee: plasma-b...@kde.org
Reporter: keithhacks-kde...@yahoo.com
CC: jpwhit...@kde.org, mwoehlke.fl...@gmail.com
Target Milestone: ---
SUMMARY
When combining a slideshow wallpaper with the "Use accent color from current
wallpaper" option, panels and windows stutter and flash every time a wallpaper
change occurs, and don't apply the new accent color in certain cases.
STEPS TO REPRODUCE
1. Go to "Configure Desktop and Wallpaper..." and set the wallpaper type to
"Slideshow".
2. Under Appearance - Colors, tick "Use accent color from current wallpaper".
3. Open various applications (particularly ones which show icons that inherit
the current accent color) and watch.
OBSERVED RESULT
Every time the wallpaper changes, the panel and dock flash opaque, the window
shadow becomes far darker for a moment, and various other graphical glitches
occur. Additionally, certain icons (in this case, folder icons with thumbnails)
don't update to reflect the new accent color, while others do.
See https://ttm.sh/wGR.mp4 (the video is too large to be uploaded here)
EXPECTED RESULT
The entire UI transitions seamlessly to the new accent color, with no visual
jankiness in between. (To the extent possible - I imagine it'd be difficult to
get GTK interfaces, for instance, to work with this.)
