The "Attach as tab to" menu is empty when there is only one window open. This results in a ugly pixel displayed as the "menu" when using oxygen. The item should be disabled if there is nothing the window can be attached to or a disabled dummy entry should be inserted into the submenu to tell the user so. On a related note: this item doesn't use the same capitalization rule as the other kwin menu items. Reproducible: Always
En/Disabling the popup is no option since it's re/build when opened. It might be possible to force down the open if it's empty but that (on an active parent action) would seem a bug as well -> dummy entry, but that (as well as Caps Change) can only happen for 4.10 due to i18n of user visible strings. Proposal for a dummy entry?
Maybe something like "No Window Available for Attaching"?
