Created attachment 189944 [details] dolphin selection rectangle
So in Plasma 6.6, for performance reasons we changed the rubberband to just be a simple rectangle, rather than using the theme's SVG. However it was not intentional that this would prevent the accent color from being used in the rubberband. And this works for me with Breeze. Which means it's an Oxygen-specific issue with its Plasma style not honoring the systemwide accent color. I recall we had to specifically enable this for the Breeze Plasma style somehow but I'm afraid I can't recall how we did it.
The new code behaves this way for all of the themes that don't follow the color scheme, so not just Oxygen. Moving to plasmashell and will send in a fix for consideration soon.

Git commit 5260f3e65c6392b5263d89d775338c3b368414af by Nate Graham, on behalf of Filip Fila. Committed on 25/02/2026 at 16:46. Pushed by ngraham into branch 'master'. FolderView: Use system accent color for selection rectangle instead of Plasma theme's The new selection rectangle in the folder view now picks up on the Plasma theme's highglight color if the theme does not follow the color scheme, which makes up most of the third-party themes. While there's merit to the argument that everything on the desktop should follow the Plasma theme's colors, in this case the inconsistency issue caused outweighs following the principle. This patch therefore restores the old behavior whereby the selection rectangle uses the system color scheme, even with themes that don't follow the color scheme.
