Bug ID: 456572
Summary: KWin effects Overview and Present Windows poor
contrast with underlay
Product: kwin
Version: 5.25.2
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: effects-overview
Assignee: kwin-bugs-n...@kde.org
Reporter: polarathene-sig...@hotmail.com
Target Milestone: ---
SUMMARY
This may be dependent upon the theme, but looked unpleasant in both default
Breeze and a third-party dark theme. For the dark theme, the underlay almost
blended in with the window colours.
STEPS TO REPRODUCE
1. Enable and toggle each of the effects.
2. "Overview" and "Present Windows" should have underlays that can look washed
out, and the latter cannot remove or adjust blur (blur effect settings don't
seem to have any effect to it).
OBSERVED RESULT
Washed out underlay provides poor contrast to windows shown, even with a dark
background. Especially with a dark theme.
EXPECTED RESULT
No underlay, or control over colour/opacity or contrast so that windows shown
stand out better.
SOFTWARE/OS VERSIONS
Tested via VMware and QEMU-KVM VM guests with 3D accel enabled:

SVGA3D => vmwgfx 2.20.0 (VMware guest)
virgl => virtio_gpu (QEMU-KVM guest)
ADDITIONAL INFORMATION
Only "Overview" effect provides an option to disable blur (which does not
affect "Present Windows" that lacks this option). I mention that so that both
effects settings can be resolved.
The related effect "Desktop Grid" behaves a bit differently (if only 1 virtual
desktop), by omitting any underlay. There's a bit of disparity between UI
elements (virtual desktop add/remove, search) between the effects.
In earlier releases, I remember "Present Windows" having a dark contrasting
underlay. Now I am given the impression it is tied to the theme/color scheme,
but not obvious as to a user what to change / look for to adjust (or if that
will affect other parts of UI visuals negatively in doing so).
I'd be happy with no underlay at all vs the current experience that gets in the
way with a washed out look, even when the background/wallpaper is quite dark
and contrasting, the underlay is far brighter.
