I have Plasma-5 and SDDM under F21. Switching sessions to another

display garbage and the session is unusable. The problem appears to be
with switching to VT1, not to the content of the sessions as such (i.e.
if I start the sessions in the reverse order the same problem happens).
I have an Nvidia card with the proprietary driver.
I tried reporting this to bugs.kde.org
but there doesn't seem to be a
category for SDDM, which I would think is the culprit.
Could you try restarting KWin after the switch? (switch to a new VT, run
DISPLAY=":0" kwin_x11 --replace &)
Such graphical glitches are usually caused by KWin not dealing with changes
