Got a HD 7750 (VERDE, Southern Islands).
In my system, the screen corruption appears with both of them radeon and
amdgpu, in the same fashion and equally work-aroundable as yours.
At this point, I'm unsure if this is a GPU driver bug, from KDE or even
Wayland, since this doesn't happen in GNOME (Wayland). Maybe they implemented
some way to switch back from TTY without screen artifacts.
By the way, this corruption doesn't occur on XOrg.
