Comment 2 for bug 1854183

Same issue here (Ubuntu 19.10) and thanks to @spirou for tracking down that it's `gtk-window-decorator`, since that's enabled me to find a workaround:

* Disable `Window Decoration` using CCSM.
* Open affected documents in LibreOffice.
* Re-enable `Window Decoration`.

This isn't restricted to `gtk-window-decorator`; I've also reproduced this bug using `emerald` as well.

I've found this affects more than just opening `.csv` files; it appears to be anything that involves a LibreOffice dialog. All in all, here are the events where I triggered this issue (all avoided by the workaround):

1. Opening `.csv` files.
2. Opening password protected documents.
3. (An important one) Single/multiple document recovery if LibreOffice crashes or was killed, with or without documents of types 1 & 2.

Using the manual installation debs (from https://downloadarchive.documentfoundation.org/libreoffice/old/) and based on this reference (https://askubuntu.com/questions/1140156/calc-shows-title-bar-only-when-opening-csv-in-compiz), I was able to track down where this bug is first triggered. `6.1.6.3` is the last working version and the first instability occurs in `6.2.0.1`. This continues all the way through to the latest release, `6.4.0.1`.
