Hi,

after a short while of usage, like 5-10 minutes, all texts disappear
from both the canvas and all menus, tooltips etc. Instead, I can only
see a number of empty boxes. At this point, I need to save and restart
dia, then everything will come back. On the console, I get a lot of
error messages related to Pango, Cairo and libfreetype. Here are a few
of these error messages:

I'm trying to use the software outside of Gnome, just with awesomewm.


Kind regards,

Hello,

Le 02/07/2025 à 17:27, Toni Mueller a écrit :
same bug than #1020531, which is fixed in testing/unstable, and thus
will be available in the next Debian release, trixie, planned for August
9th.

I just setup a fresh Debian testing VM with awesome window manager and
failed to reproduce the bug, which was a bit expected since the bug
should be fixed in testing.


Also, I don't understand why this bug is tagged ftbfs: it doesn't
mention a build failure.


Philippe.
