Actually not the stuff itself becomes slow all of a sudden, but the needed
optimisations for this hardware often is removed from code, or efficient
functions have been replaced by resource consuming eqivalents. Modern
implementing of former hardware functions in software (like sound processing,
video codec processing etc.) slows down clasic CPUs, while the dedicated
hardware idles, since for everything the CPU is used. Hence some updated
software runs slow on it (while other with same functionallity does not). A
good example is the nouveau driver vs. proprietary nvidia driver. With the
latter all GUI menus open immediately, without any delay, while with nouveau
driver you'll have to wait sometimes more than 8 seconds for a response after
click. So, if you chose your OS, the kernel, the software, the drivers and
libraries carefully, you can see runing the so called deprecated hardware as
fast as new one. It's an amazing experience, btw, this is just like you can see
an old 1960s racing car catch up easily with any of the todays lower
middle-sized class cars. But this is not the place for this basic discussion
about old hardware I believe, so I won't go into detail. Just one last
additional info: Libreoffice is one of the great programs running fast and
fluent on old hardware, even in its recent versions.

You'd better nudge nvidia to allow devs of xorg to update the nvidia kernel
modules for all their older video cards, it is missing a tiny blob only, then
people simply could upgrade to buster and bullseye. Its not the user not
willing to update his system, but the hardware manufacuter. (Was quite tricky
to force the last available proprietary nvidia driver for this notebook GPU run
even on buster, but it was worth it.) Anyway, since I wasn't able to make it
work on bullseye by now, the following test was run with nouveau driver instead.
Concerning the bug:
I've managed to run a test for Libreoffice on bullseye now, using a Live USB
medium. Doesn't count whether the needed propriatary nvidia driver isn't
available for bullseye, since for this testing the nouveau graphics driver is a
basic replacement (not fit for everyday usage due to generally heavy delay in
response, broken in dualhead and on resume after suspend on this device,
anyway, this driver is the main issue keeping me from upgrading to bullseye
completely.)
The interessting result is: I found the issue described by my original report
(from backport to buster) present also in the non backported version on
bullseye. Behaviour exactly as described above.
