Created attachment 128271 [details] Screenshot of Slides Pane window with the misplaced popover. I use LibreOffice 5.2 on Fedora 25 (Wayland + GTK3) and I have a problem that stayed from 5.1 on Fedora 24. I've mistakenly undocked the slides pane in Impress, but I couldn't return it back because the window got wrong size that doesn't show the contents of the window, but only the title. When I try to drag the tilebar, Impress crashes. There's also a misplaced popover (tooltip) outside of the window pointing to a slide. Sometimes when I hide the slides pane, and show it back (from the View menu), it gets docked back to its place in the main window, but when I close Impress and open it back, I lose it again.
I've started libreoffice from command line, and reproduced the issue (dragging the titlebar of slides pane window). I got those errors: (soffice:31051): Gdk-WARNING **: No grabbed seat found, using the default one in order to map popup window 0x5560e7f6$ 1b0.

Created attachment 128272 [details] Undocked Slides Pane in different but still small size I've just known how to dock the window again (I know that I can drag the window, but this can't happen now) by pressing Ctrl+Shift+F10. Now, I switched between docked/undocked window multiple times and closed/reopened the program too. Every time, the Slides Pane window gets different window size that can't be resized or dragged from its titlebar. All sizes are small but some of them show part of the window contents.
Yeah, this whole docking window problem can't be done directly with gtk3 under wayland so I ended up disabling the whole floating docking windows when under wayland with https://cgit.freedesktop.org/libreoffice/core/commit/?id=a6d324f30bd5cfd09d54614d8df67b7857550429 and already floating docks like this one are auto-docked on startup "fixing" the problem
