This font delay problem in libreoffice-writer 7.3/7.4 seems to be a combination of libreoffice-gtk3 and Nvidia proprietary driver. The problem appears with default desktop enviroment and with gnome classic. Problem appears in wayland and xorg.
Ubuntu 22.04 GPU Nvidia 750ti (Nvidia Driver 515) Libre Office 7.3/7.4 Extreme Font Menu Delay when: Nvidia driver - Installed AND libreofffice-gtk3 Installed No Font Menu delay when: Nvidia driver Installed AND libreofffice-gtk3 Not Installed Nvidia driver Not Installed AND libreofffice-gtk3 Installed Nvidia driver Not Installed AND libreofffice-gtk3 Not Installed I can confirm David White. No problem in Mint 21. BUT As soon as i install gnome and log into a gnome session with Mint 21, then the extreme font delay will appear in libre office. When i log back into a mate session then the font menu behaves as it should. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1969709 Title: libreoffice font selection unusably slow Status in fontconfig package in Ubuntu: Confirmed Status in libreoffice package in Ubuntu: Confirmed Bug description: Trying to scroll through the font list in the menu bar, I experience an unacceptable degree of lagging. Just popping up the dropdown list takes 7-10 seconds and the system takes the same amount of time to respond to perform individidual scrolling gestures. The CPU jumps to 100% and the whole system becomes unresponsive. I have tried deb, snap and even the packages offered on the site of the LibreOffice project. They all manifest the same behaviour. The only thing that works is disabling font previews. I have downgraded to 7.2 for now, which appears to be unaffected. I have contacted the LibreOffice team and they tell me that this should be solved by fontconfig 2.14. Unfortunately, Ubuntu 22.04 is shipping 2.13...
