SUMMARY Operating System: openSUSE Tumbleweed 20220813 KDE Plasma Version: 5.25.4 KDE Frameworks Version: 5.96.0 Qt Version: 5.15.5 Kernel Version: 5.19.0-1-default (64-bit) Graphics Platform: Wayland Processors: 8 × 11th Gen Intel® Core™ i7-1165G7 @ 2.80GHz Memory: 15,4 GiB of RAM Graphics Processor: Mesa Intel® Xe Graphics Manufacturer: Dell Inc. Product Name: XPS 13 9305 STEPS TO REPRODUCE 1. Enable the Desktop Effect called Dim Inactive (Darken inactive windows) 2. Use ALT+TAB to switch tasks OBSERVED RESULT Task switcher is affected by dimming although it's the foreground "window" EXPECTED RESULT Task switcher should NOT be dimmed since it's in the foreground window, and definitely the one the user wants to focus when invoking the task switcher. Having the contents of the tabbox dimmed makes it harder for the brain/eye of the user to detect the window to jump to.
Although this is minor, just chiming in to say it's still reproducible.

I am also annoyed by this, on Fedora 40, Plasma 6.1.3. I like to do significant dimming on the inactive window(s), but that makes the tabbox barely usable. There's no way this effect should be applying itself to the tabbox/task switcher dialog. The fact that this issue has been open since late 2022 is gravely disappointing.
Reproducible in 6.2.2 aswell

not reproducible on 6.4.1
It seems resolved only for the default thumbnail grid, so not sure if that makes this bug resolved.
I just tested on Fedora 41, Plasma 6.4.1, with the "Large Icons" task switcher that I normally use. Definitely not resolved for me. The task switcher is still being dimmed. Setting the darkening strength to something like 90 makes it very obvious. On the other hand, the "Thumbnail Grid" task switcher that I set up for the in-app window switching shortcuts in the "Alternative" tab is not dimmed in the same way by the desktop effect. Seems unaffected no matter what the dimming strength is set to.

After being used to the dimmed Large Icons task switcher for so long I almost thought something was wrong with my display when the icons were suddenly full color and full brightness. Thanks for fixing this, Vlad.
