thank you for your bug report, that seems like rather a gtk/wayland/gnome-shell issue than a libreoffice one though

[Richard (ismail-a)]

I got lots of these, which is tedious in combination with losing document styles.
General: select the n
Just now: Copy the document name from File - Properties - [select the name of the document] control+c, click Cancel
Try to paste into the Document text: The soffice.bin process terminates and all LibreOffice windows close

[Richard (ismail-a)]

Again:
When opening a recent document from the initial blank document produced by libreoffice --writer on a third external display, while LibreOffice was already running, all LibreOffice windows disappeared

The libreoffice command did not exit

On control+C, relaunch, no windows appeared

On restart of GNOME/Wayland, the recovery dialog appeared after 2 min 10 s, which is 2 min more than normal

- This is tedious with bug/1649295 LibreOffice Writer docx fails to load styles
- The initial crash that forced a relaunch of LibreOffice was caused by bug1647084 i915 multiple display halt system when moving windows
  - for unknown reason A LibreOffice calc window jumped from the right external display to the left external display
  - when it was dragged back across the internal display, the window unexpectedly jumped to the top-left position and GNOME Shell froze

[Richard (ismail-a)]

Apparently, windows switch displays for no apparent reason. Is it so that LibreOffice moves all window to a non-existing display, ie. hides them?
