..using which web browser? I tame brave, firefox etc with e.g.:
niceload -L 18 -n 19 -M 6G -N -q chromium --disable-machine-id \
--disable-remote-extensions --disable-crashpad \
--disable-crash-reporter --enable-webgl-draft-extensions \
--enable-webgl2-compute-context --enable-unsafe-swiftshaderC \
--ignore-gpu-blocklist & # and then: cputool -c 125 -l 17 \
--pid-pgrp $PID-of-the-top-pid-of-the-chromium-process-group
or the easier, as root: cpulimit -e chromium -l 75 -c 1 -b

..ssh -X or in your lan, ssh -Y no longer works?
Chk your ssh and X set-ups, e.g. X needs to -listen,
not -nolisten nor -novtswitch.



..my impression is Wayland, systemd, usrmerge, gnome etc
schemes are schemes meant to reduce GNU/Linux from a
multi-user OS, down to a single-user OS, with switches
like -nolisten, -novtswitch and the reluctant bug fixes
that lead Enrico Weigelt to fork Xlibre from Xorg.

..tried Xlibre yet?

Scenarios always come in sets of three:
best case, worst case, and just in case.
