When we make C++17 a requirement for LibreOffice at the end of 2018 the version of coverity provided by scan.coverity.com no longer worked for us. In July 2019 a newer version of the coverity tooling was available which supported C++17 and analysis resumed.
Prior to losing coverity support we had a defect density (i.e. defects per 1,000 line of code) of 0, on its return this had inflated to 0.06 due to both new defects introduced during the down period and old defects newly detected due to additional checks introduced in the new version.
Today we're finally back to 0

Native GTK Dialogs in LibreOffice
LibreOffice Native GTK Dialog Status
The LibreOffice UI was traditionally implemented with its own VCL toolkit which via theming emulated the host desktop toolkit.Then we migrated the file format the dialogs were described in to the GtkBuilder file format. But still implemented with VCL widgetry, though with additional GTK-alike layout widgets.
Then migrated the translation format to gettext .mo files, which added plural form translation support we had lacked.
Then incrementally migrated the code driving the dialogs to a new API with two implementations, one for VCL widgetry and one for GTK.
Over the last few major releases the GTK version of LibreOffice has increasingly had true GTK dialogs and less VCL dialogs and in master, as of this week, there are now no direct uses of the VCL dialog APIs.
There are still some non-dialog utility windows and other elements to port over, but dialogs are complete.
LibreOffice has a lot of UI. There are 1029 XML UI definition files in master. 480 definitions of a GtkDialog and 75 additional GtkMessageDialog definitions. The remainder of the files typically describe a single page of a Notebook, Assistant or Sidebar, often appearing in multiple dialogs.
Here are some gifs of a small set of the dialogs from master under Fedora 31, taken under Wayland with peek, showing some of the stock animations of the default GTK 3.24 Adwaita theme

LibreOffice color selector as GTK widgets
Here's what the native GTK widget mode for the color picker looks like at the moment under Wayland. A GtkMenuButton displaying a color preview of the currently selected color and a GtkPopover containing the color selection widgetry.
While under X, because there the GtkPopover is constrained to its parents size, falling back to using a GtkWindow to contain the widgetry

Some Native GTK Dialogs in LibreOffice
So for these dialogs this means f.e that the animated effects for radio and checkbuttons work, that the scrolling is overlay scrolling, and that the visual feedbacks that scrolling has reached its limit, or that available content is outside the scrolling region are shown. In the above demo, the GtkNotebook is the real thing.

native GTK3 message dialogs
In LibreOffice 6.1, when the GTK3 backend is in use, the message dialogs are now native GTK3 message dialogs rather than vcl message dialogs using GTK theming.
So they are now true GTK dialogs and they look like...
while before they looked like...
We have 475 message dialogs directly instantiated in LibreOffice and 89 indirectly instantiated via GtkBuilder .ui files.
We've changed the format our dialog, etc. translations are stored in from our own legacy custom format to the more commonplace gettext .mo format. In the case of a message dialog described via a GtkBuilder .ui file, we now use GTK's own GtkBuilder to load the .ui, and GTK's own gettext integration to localize it from our new .mo format translations.

gtk3 + broadway + libreoffice
Out of the box in Fedora 26 I see that our gtk3 version of LibreOffice mostly works under broadway so here's libreoffice displaying through firefox. Toolbar is toast, but dialogs and menus work.

Discrepancy Report #107743
Short (1996) little article about a bug in the shuttle starboard manipulator arm display position.
Spoiler:
Spoiler:
A half-dozen pages of forms detail [the error] ... the most remarkable thing about the error and its paper trail. “There is no starboard manipulator arm”
