@Daniel: Maybe I answered a bit hasty. I see this issue over and over again without any Nvidia driver. But I do have a Nvidia card, if that may be related.
Not sure about the root cause of this bug. We know that it happens with the Ubuntu font and that that font was changed in the mantic cycle. But is the font change to blame, or is it maybe some inability in Gtk/Pango/whatever to deal with a font change smoothly? Or is it a limitation in fontconfig? Would the issue show up if some other font in use had been changed, even if it was not set via the font-name dconf value? Those are thoughts in my head. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ubuntu-meta in Ubuntu. https://bugs.launchpad.net/bugs/2034986 Title: some text became unreadable during a distribution upgrade Status in ubuntu-meta package in Ubuntu: Confirmed Status in ubuntu-release-upgrader package in Ubuntu: In Progress Status in ubuntu-meta source package in Mantic: Confirmed Status in ubuntu-release-upgrader source package in Mantic: In Progress Bug description: I was upgrading from Lunar to Mantic the other day and left a couple of applications open during the upgrade process.
