STEPS TO REPRODUCE Open multiple windows of the same app, like opening multiple images. OBSERVED RESULT The lack of outline around the preview of the window currently in focus makes it look like a bug. EXPECTED RESULT There should be an outline around the preview of the window currently in focus, so the user can easily understand the feature.

Created attachment 189794 [details] Exactly like this, but just the outline.
I'm not convinced this is necessary or helpful - people will recognize that it has scrolled to the window they have open; it's in the foreground on screen at that time.
I don't really understand. There is an outline and a background? Why do we need another one around the preview itself?

The idea is to show that this is the current window that has focus, so that if you have a grouped task tooltip with multiple windows (which, in case there are enough of them to not fit the screen, may open scrolled to one of them) it's clear which one is the currently active window, if there is one. Now that I think about it, having the window title be in bold though may be appropriate - it would also help with thumbnails disabled to help orient yourself in the tooltip.
It works perfectly when the window preview can be on the dead center, but by the end of the previews it will be a bit difficult to track if you have many windows that look similar, with 100% scaling in a 4k TV or a ultra-wide monitor. It's not like they can simply be hovered over by the cursor and the window will fade in (or pop if the Animations are deactivated).
Oh I think I get it now. So when you have three previews, and one of them is in focus, we should indicate which one is in focus. I think setting the text bold is good idea.
What if the filename is 𝗕𝗼𝗹𝗱𝗧𝗲𝘅𝘁😂😂😂.jpg
Window titles (as displayed in the tooltip) are always plain text, so there's no danger of that.

Git commit 8890bac8dfd624f19a5966ab1b03dc2dc1bbb0bc by Christoph Wolk. Committed on 17/03/2026 at 21:47. Pushed by cwo into branch 'master'. applets/taskmanager: highlight active window with bold text In grouped tasks, it can be helpful to indicate the currently active window (if one of the task's windows is the active window) to provide the user with some contextual clues to help them orient themselves in a potentially long list (helpful in particular with auto-scrolling to the active window in case there are more tasks in the popup than can be displayed). But this indication should be subtle, as it is also often irrelevant and making it too visible could be distracting or confusing. This change marks the currently active window in grouped tasks in bold.
