After update from Kubuntu 22.04 to 23.04 via 22.20 LibreOffice opens with 1 dimensional window

[Tony Middleton]

I upgraded a machine from Kubuntu 22.04 to 23.10 and then immediately to 23.04. After logging on to 23.04 I tried to open LibreOffice documents but only had a vertical line on the screen. After some experimentation I found that this line was a window of zero width and it was possible to use the mouse to widen to a usable window. Opening subsequent documents was OK.

I have now recreated this on VirtualBox and it seems that the problem occurs if you don't edit documents at the 23.10 stage. Steps to recreate.

1. Install Kubuntu 22.04, run apt update/dist-upgrade.
2. Close, take snapshot, reload
3. Create LibreOffice documents, eg calc, impress and write, enter random text.
4. Close, take snapshot, reload
5. Upgrade to 22.10
6. Close, take snapshot, reload
7. Log on, edit each document, add more random text.
8. Close, take snapshot, reload
9. Upgrade to 23.04
10. Close, take snapshot, reload
11. Log on and open documents

Following the above script which includes document updates under 22.10, the documents open correctly in 23.04.

Repeat the above, omitting steps 7 & 8 so the documents aren't edited under 22.10. The documents open as a zero width window in 23.04.
