I don't think XServer is crashing as the .xsession-errors shows errors but
not a restart and Xorg.0.log shows no errors or restart.
My guess is that TDE is encountering serious errors that disrupt TDE
operation but that do not cause X to crash.
Are there any information listed in the XOrg log?
Lots of X startup info but no errors in Xorg.0.log. However
.xsession-errors mostly consists of high-speed repeats of this approx
ten times per second. Sometimes there are a lot more stale lockfile
messages and sometimes a different resource id appears but it's mostly
like this.

There is none of the above when the second display is disabled and TDE
is working fine.
If you try "xrandr -q" from Konsole, will it
print both monitors?
Here is xrandr -q with the second monitor DISABLED in nvidia-settings
and TDE 14.0.7 PSB working fine on my primary display on DP-2 and the
disabled monitor on HDMI-0.

Here is the xrandr -q with the second monitor enabled as screen :1 in
nvidia-settings. I had to use Failsafe mode to get this initially but
(see below) after I found I could kill one of the kdesktops and stop
the flashing I got the same randr -q result as in Failsafe mode.

Note that there is no sign of the second display even though TDE is
throwing up a blue background and occasional screen unlock dialogs
on the second display. The second display should be in screen :1
and not used by TDE in :0.
The "screen is locked" dialogs appear randomly on one screen or the
other every half minute or so - much earlier than they should appear.
The flashing stops while the screen unlock dialog is present so I can
type my password and return to the flashing.
Here is the relevant portion of a Factorio log in the dual monitor
configuration, using a TDE Failsafe login which works fine albeit
it only gives you a root konsole login. Here I have started Factorio
from non-root konsole in Failsafe mode in :0 and told it to run on :1.

You can even start kicker from a non-root konsole in Failsafe and things
mostly work.
I just discovered that in the two display configuration TDE is running
kdesktop on both screens. If I guess right and kill the unwanted
kdesktop the flashing stops and TDE appears usable.
tdmrc has the default, unchanged from 14.0.5, including
StaticServers=:0
ReserveServers=:1,:2,:3
I haven't tried changing this yet. What on earth is an on-demand
(reserve) server?
