Hi all!
Good news:
The Libreoffice backport from bookworm seems to fix this issue. I've checked
this on different kernels:
Besides of the 4.9.0 kernel I've tested this on
linux-image-5.10.137-antix.1-686-smp-pae
linux-image-5.10.142-antix.2-686-smp-pae
linux-image-5.10.0-18-686-pae (signed)
linux-image-5.10.0-19-686-pae (signed)
and additionally from on most recent one from Bullseye-Backports:
linux-image-5.19.0-0.deb11.2-686-pae
Really great thing is, that this most recent backport kernel comes up with
noveau driver properly now, this is first time I see noveau running mostly
equivalent to old proprietary driver stuff from nvidia. Everything efficient,
fast and fluent, clear view now. Great work, whoever did this, many thanks!
This allows me now to switch to 5.x kernel series finally, dumping old nvidia
proprietary driver stuff (which was single way to achieve this result until
now). But unfortunately this doesn't fix Libreoffice issue all the same: The
most recent Libreoffice bullseye version (not the one from backports) shows the
originally described issue on all these kernels listed above. Only the
Libreoffice backport doesn't show this behaviour any longer, CPU load from
Libreoffice backport (details below) stays perfectly normal when it looses
focus. Checked for several hours. Many thanks!
Maybe you can transfer the fix to the stable bullseye version, so people can
run the default version instead of backports, in order to get security updates
(above you've stated there are none on backports, which would be bad).
