Description

I have a 2560x1440 screen, and everything was fine in the past

After upgrading to xubuntu bionic 18.04 I have a weird behaviour: every time I reboot the dpi value is changed. Well, really I don't know whether it's the dpi value or something related to antialias... The situation is that in google chrome the characters are bigger than before rebooting; not only the characters, the browser acts as the dpi value is bigger. But the dpi value in settings -> aspect doesn't show any change

Anyway, in order to restore the normality I must change the antialias value is settings -> aspects: touching something there I get my screen come back to normal dpi.

I don't get this bug on a smaller screen.
