sddm login screen flashes and disappears before i can enter anything

The workaround fixes the problem on my system.  I did a fresh install from the latest lxqt testbuild, and did d-u right after installation.  My graphics card is AMD R7-200 (HD8670 RS340X).  This is an older Dell desktop with i5-4590 processor.

The note from the bugreport has solved the problem for the time being.

I create a file /etc/X11/xorg.conf.d/10-radeonenvrac.conf
with in it:

Section "Device"
     Identifier "radeaonenvrac"
     Driver "radeon"
     Option "Accel" "no"
EndSection

It really only seems to be a temporary solution, let's hope that the bug will be solved for good.

I would like to thank everyone who sacrificed their free time to fix this bug.

It would be interesting if this bug hits also a Wayland Session!

Even when I start "Plama Wayland", the start screen animation appears briefly. An error message is displayed very briefly and then it is black.

Error message: 'ksplashqml was terminated unexpectedly'

I can confirm that.

I have the newer version of libgl1-mesa-dri and libglx-mesa0 and am still getting a blank login screen except for the boxes used to enter the username and password. I can enter the username and password carefully into the boxes, but, cannot see what I am typing. If I type them both correctly lxQT comes up and the OS runs fine. This is on my old Asus EEEpc that's been running siduction lxQT for many years.
