SUMMARY
My machine is set up with 3 screens in a PLP format (portrait-landscape-portrait); Screens are 1920x1200 (side) and 2560x1440 (centre).

If I select the maya theme for SDDM, I get an unusable login screen layout with-

1) The side screens rotated by 90 degrees
2) A giant onscreen keyboard (presumably for accessibility) covering roughly half of each screen. This hides the icons for selecting users, and the text box for the password, making it very difficult to log back in again and undo the config change.

STEPS TO REPRODUCE
1. Select the maya the for SDDM
2. Log out

OBSERVED RESULT
Unusable login screen with a soft keyboard covering more than half of the display area

EXPECTED RESULT
A login screen that looks something like the thumbnail shown in the configuration tool, and is usable
