Created attachment 152091 [details] screenshot of the bug SUMMARY In Overview effect, the content of the active window (in Breeze theme) is in the inactive color (light gray), while the title bar is in the active color (dark gray). STEPS TO REPRODUCE 1. Start Dolphin. 2. Trigger the Overview effect. OBSERVED RESULT Dolphin's titlebar is dark gray, while content area is light gray. EXPECTED RESULT Titlebar and content area should be in same color. SOFTWARE/OS VERSIONS Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.25.90 KDE Frameworks Version: 5.98.0 Qt Version: 5.15.6
In fact, this is just the window using its "I'm inactive" visual state. And from KWin's perspective, the window is inactive. Heck, from the user's perspective it's inactive too; what's active is the Overview effect! :) The only thing we could really do here is have KWin lie to the last-active app and tell it that it's still active when Overview launches, but that's a can of worms and I don't think this is a significant enough visual unexpectedness to warrant it.

Then I think kwin should draw the titlebar in inactive color to match. If you open two Dolphin windows, one of them active, then trigger Overview, both windows are in inactive color, but titlebars are in different colors.

If you open a Dolphin window, enter Overview. then exit, you'll see that the content area changes to inactive color and back, but the titlebar doesn't change color at all.
Oh I get it now. Seems like a Breeze bug?

(In reply to Nate Graham from comment #4) > Seems like a Breeze bug? I tried Plastik decoration. Same problem. (See the attachment above. Note different text color in titlebars.) So it's more like a bug in kwin, than in specific decorations.
In that case you're probably right, yeah.
