Inactive Blur - Yakuake No Blur

[FlyingWaffleDev]

When using the Inactive Blur wallpaper plugin it does not activate when the Yakuake drop-down terminal is activated. If any other window had triggered the blur, activating Yakuake cancels it even though I would expect Yakuake to be the new "active" window and keep the blur. Same behavior on both my desktop and laptop (both running v5 on Gentoo).

Yakuake is filtered from the taskbar. I use the same QML model that the panel taskmanager widget uses, so it won't treat Yakuake, or panel widget popups, as "windows".

I'm unfamiliar with the internal workings of Qt/KDE; is it possible to per-app exceptions for widgets like Yakuake?

Also, Yakuake does intermittently register as a "window"; I can't replicate this consistently, but when it happens the inactive blur effect triggers and a Yakuake icon is added to my panel of running windows.

I'm re-using the taskmanager widget's "window list" as I'm too lazy to write a C++ plugin to solve this issue. This plugin wouldn't be able to distribute on the KDE Store if it required a C++ plugin anyways.

Note to self: Here's the hardcoded (because it's not exposed as a TaskModel property) bool that needs to be flipped.

I'm more likely to rewrite this WallpaperPlugin as a KWin Effect (to also blur the desktop widgets) if C++ is necessary. Both are unlikely to be written by me in the near future.
