Description redmoon1945 2023-05-26 14:09:18 UTC 
Description:
Running Kubuntu 23.04 with 2 monitors : couple of days ago LibreOffice get updated to 7.5.3.2 (non flatpak). Since then, I have got all the times horrible screen artefacts in LibreCalc (misalignment affecting lines and fonts). Goes away if I scroll (refresh). So quite annoying but does not crash LibreCalc not corrupt data

Steps to Reproduce:
1.open a new spreadsheet
2.type some data anywhere
3.very rapidly, the artefact appears

Actual Results:
there are discontinuity in the display, as if a section of the screen is shifted one pixel. Fonts rendering and lines are affected. Same effect if I switch to Safe Mode. Same problem also on any of my 2 monitors (the laptop and a Dell S2719DC attached with USB-c Thunderbolt 4 cable.

Expected Results:
No shifting should occur


Reproducible: Always

I found bug 152930 which looks the same. Are you also using HiDPI screens?
