[solved] Login Screen text missing

Asked by GerdG on 2018-05-12

After updating to Ubuntu 18.04 LTS the login screen shows no user names, just the user icons.
In the follow up screen some letters are missing e.g. "Cancel" is written "Ca l ", see screenshots.

If I toggle the text settings "large texts = on/off" the texts appear. (In this dropdown menu single letters are missing, too.)
So I think it might be a rendering problem.

Any hints?
Thanks in advance...

I suggest you report a bug. What is the output of:

dpkg -l | grep dm

Thanks
