Bug Description

See this reported bug (screenshots) that affects Kubuntu Artful Aardvark Beta 1:
https://github.com/sddm/sddm/issues/892

Text is invisible, changing theme or font does not help. Same thing happens for the lock screen, where entering password shows whitespace, but no asterisks.

Interesting though, if you click the place with the mouse, where the "show password" eye icon should be, the password text is visible (or the grey "Password" is shown). But if you click it again, the text disappears.

The eye icon is invisible during the log in, but visible on the lock screen.

The text cursor is always visible and moving.

sddm version is 0.14.0-4ubuntu1

The letters on the visual keyboard are invisible too.

Correct.

Can this be debugged somehow? SDDM log is not helpful.

I'm afraid, the problem can be in some related QT or KDE library: I've tried to downgrade sddm and sddm-theme-breeze to the versions from zesty (0.13.0-1ubuntu5 and 4:5.9.4-0ubuntu1 correspondently), but the problem is still there.

KDE version 4:5.10.5-0ubuntu1, QT version 5.9.1+dfsg-5ubuntu2.

PS The user icons are also invisible.

Apparently, only English locale works correctly. Any other locale triggers this bug.

After updating one of these packages I don't have this problem anymore. Unfortunately, I cannot pinpoint the exact package that fixed it.
