I'm also affected by this bug.
There is always a "RIP Code" warning available through dmesg, after crashing of sddm-greeter.
 
Same graphics:

Advanced Micro Devices [AMD/ATI]
RS482M [Mobility Radeon Xpress 200]
driver: radeon

Acer 5100 with Turion TL-60 CPU

I use Lubuntu.

My work around for anyone wanting something usable is Ctrl-Alt-f2 to the
terminal, logging in and installing xdm or wdm, at the end of the
installation it lets you choose a new display manager, choose xdm if it
is what you installed. And it works, you can log in and use it normally.

I have not tested other Desktops Environments. Everything works under
LXqt: 3D Screensaver, Firefox, video playing, etc.

So, If this is a mesa bug, why everything else works? And only sddm-greeter dies?
It stands to reason that sddm-greeter does not do anything more complicated or graphics intensive than Firefox, Mplayer or the 3D screensaver.
