Comment 0 for bug 1940836

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 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).

I'd be perfectly happy to run on GTK2 as workaround, if that allowed persistent copy/paste :)
