Created attachment 150301 [details] highlighted leftmost column items are bluer This has to be the most subtle bug I've reported so far :P In the Status and Notifications (is it called HiddenItemsView) popup, the translucent focus highlight is drawn on top of items in the leftmost column. Items in other columns have the highlight correctly behind the icon and caption. It's kinda really difficult to see with Light Breeze Plasma theme but is more visible in Dark theme. .... Disclaimer: I didn't go through the code nor know how it works, but I think I might have found some kind of clue. plasma-workspace/applets/systemtray/package/contents/ui/items/ItemLoader.qml sets z = x which I'm just guessing affects the items' z ? (Looks like it's to make tab key navigation order work correctly; explained here: https://github.com/KDE/plasma-workspace/commit/73d13d1bfee620c76709ea39a9b7948323887059). So perhaps that results in leftmost items with small x getting z that is not bigger than the highlight's z ? (or something) I may be entirely wrong in my reasoning, of course, but setting z = x+1 seems to fix the appearance, so at least it seems to be somehow related. KDE Neon User, Plasma 5.25.2
Great investigation. Can confirm, and it seems like you found the exact cause of it, indeed. Can you submit a merge request with your proposed fix (which seems reasonable to me given the current architecture) at https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/? Thanks!
