src/sys/dev/syscons/scmouse.c dynamically allocates the cut_buffer
array and computes the cut_buffer_size from the screen coordinates.
So the buffer should be able to hold the whole screen's content. Do
you change the screen's dimension after using the clipboard?
BTW you don't mention your system's `uname -sr` output.

Have a look at PR kern/21156: ("[PATCH] inconsistency in scmouse
vs xterm behaviour"). The "squeezing empty lines" you experienced
is mentioned there and sobomax already fixed two of the three items
last autumn (although I cannot tell if it has been MFCed since I
run the local patch here).
BTW do I still feel that the _assumption_ "when there are
characters at the end of one screen line and at the start of
the next screen line it's only "optically" wrapped and there was
no line feed in between" is more appropriate than the current
behaviour. So I still suggest the one line patch from my last
followup (from 9 Dec 2001) for consideration. The only "clean"
solution to this - as discusses in the PR - was to keep track of
how the screen content was drawn and probably is too much to ask
for a console driver.
