I am using ObjectDock 18.104.22.1681, W7 x64. Tabbed Dock is set to top of monitor, always on top, autohide reveal
The dock itself stays on top of windows as it should, however frequently (mostly?) the Shortcut Title text will be behind the window.
And it happens with any window, maximized or not, the dock will be on top as normal and the Shortcut Title text will be hidden behind the window.
And it is being displayed, the top edge of the windows are transparent so I can see the text changing in the back as I mouse along back and forth over the icons.
I my case I have many identical icons in a tab, (spreadsheets, RDP targets, etc.) so the title text is very important.
