When using the clock/prime hub mode screensaver it cuts off the bottom part of the 'g' in 'eighteen', but only for the minutes and not the hour. It's a weird one because at eight minutes past the hour, the 'g' in 'eight' is fine.
I'm on the beta version of Android so bugs are expected, but Google say they can't reproduce this one. Has anyone else seen this?
I had this problem, and it was definitely a theme issue.
https://askubuntu.com/a/1372318 may be helpful in setting a theme just for libreoffice, it you're using GTK themes. (Basically, override the GTK_THEME variable in the .desktop file). I haven't tried it myself since I just switched to a different theme.
