** Description changed: - Before updating to Ubuntu 24.04, I do sudo apt upgrade to update my - packages on Ubuntu 23.10 first. + [UPDATE] Updating to Ubuntu 24.04 DO NOT SOLVE THIS PROBLEM + Before updating to Ubuntu 24.04, I do sudo apt upgrade to update my packages on Ubuntu 23.10 first. + [UPDATE] Updating to Ubuntu 24.04 DO NOT SOLVE THIS PROBLEM Then I found that every program in GTK4/Libadwaita renders with missing characters, even gdm (I cannot take a screenshot of gdm, but the problems are the same). I toggled "Antialising" in GNOME tweaks, and some characters return TEMPORARILY. Then I opened a new GTK4/Libadwaita program, problems re- occur. AND I FOUND THAT the "Graphics" Section (the driver name) has been changed to "AMD Readon 680M" after the update (I think it is something like "AMD Rembrandt" before sudo apt upgrade). (I toggled in GNOME tweaks to make the window display graphics info; if I re-open it, fonts will be missing again) If I hover on the place where text should display, some texts may display but icons would not. This problem affects my life qualify, thus I need to make clear where it is the problem. GTK4? Libadwaita? Graphics? Ubuntu? Because problems does not occur on GTK3 based apps, thus I can submit this issue in Firefox. I tried to open GNOME Calendar and use journalctl to capture logs Apr 26 09:02:00 amber-XiaoXinPro-14-ARP8 gnome-calendar[4462]: gcal_range_union: assertion 'a != NULL' failed Apr 26 09:02:00 amber-XiaoXinPro-14-ARP8 gnome-calendar[4462]: gcal_range_contains_datetime: assertion 'self' failed Apr 26 09:02:00 amber-XiaoXinPro-14-ARP8 gnome-calendar[4462]: Unable to bind the same property on the same instance Apr 26 09:02:00 amber-XiaoXinPro-14-ARP8 dbus-daemon[898]: [system] Activating via systemd: service name='org.freedesktop.GeoClue2' unit='geoclue.service' requested by ':1.103' (uid=1000 pid=4462 comm="/usr/bin/gnome-calendar --gapplication-service" label="unconfined") Apr 26 09:02:00 amber-XiaoXinPro-14-ARP8 systemd[1]: Starting geoclue.service - Location Lookup Service...
