Description:

I recently upgraded to plasma 5.23 under Wayland with LibreOffice Fresh (7.2.2-1).

Under this environment, LibreOffice defaults to using the Qt5 framework for the GUI (kf5) and it has proven to be extremely unstable, especially in LibreOffice Draw. A sure-fire way to crash Draw is to make a simple text box, add some text, and then change the font. Instant crash with no debug information to the console. Disabling hardware accelerated graphics, the background cache, and running in safe mode do nothing to fix the problem.

However, running LibreOffice with the GTK3 GUI backend (SAL_USE_VCLPLUGIN=gtk3) fixes these problems and the program appears to run fine under my Wayland Plasma desktop. I haven't tested trying to get Libreoffice running under XWayland, but this might fix some of the problems too.


I'm putting this bug as medium severity only because the GTK3 work-around avoids the crash, but in the context of the kf5 plugin it should be a high priority bug.If this is a deeper bug that you can't fix, some documentation in the Libre Office Wiki entry could help others to avoid the bug in the meantime.

Additional info:
* package version(s):

libreoffice-fresh 7.2.2-1
gtk3 1:3.24.30+62+g8d04980f38-2
qt5-base 5.15.2+kde+r243-1
qt5-wayland 5.15.2+kde+r34-1
kio 5.87.0-1
kwayland 5.87.0-1
plasma-wayland-session 5.23.0-2
plasma-workspace 5.23.0-2
kwin 5.23.0-1


* config and/or log files etc.
* link to upstream bug report, if any

Steps to reproduce:
1. Run lodraw with the kf5 backend (SAL_USE_VCLPLUGIN=kf5) under Wayland [Kwin 5.23 in particular]
2. Add text to an empty document.
3. Attempt to change the font of the text.
This task depends upon

what's the status of this? did you report it upstream?
Comment by Curtis (foxcm2000) - Thursday, 25 November 2021, 18:36 GMT
It seems to have resolved itself after one of the many point-releases of the qt5 packages. I'm requesting bug closure. Thanks for the reminder!
