Public bug reported:
I'm on a MATE 20.04 machine, with Nvidia proprietary drivers (for
reference, can't use Nouveau, since my machine doesn't boot with it).
Libreoffice Calc renders slow. The delay is very noticeable, even when
just typing characters.
If I remove the GTK3 styling (`libreoffice-gtk3` package), then the
rendering speed is fine (but of course, the program is unstyled, with
some workflow consequences).
I've tried to run on GTK2 (`libreoffice-gtk2` package installed), but I
see Calc as unstyled, so it seems it's not actually running on GTK2.
I've also tried to disable HW acceleration, but there is no improvement.
I don't experience this slowness on any other program on my
installation.
I've noticed that when there's a delay, the Xorg process CPU occupation
skyrockets (depending on how fast I type, it may go even to 100% (single
thread)).
I've reproduced the same problem on all the LO versions, from the
default (6.4.7) to the latest (7.2).
The kernel version doesn't affect the problem as well (experienced on
different 5.x versions).
I'd be perfectly happy to run on GTK2 as workaround, if that allowed
persistent copy/paste :)
