Erasing libreoffice-gtk3 will stop the flickering on KDE and allow me to
enter Chinese.
Using libreoffice-gtk2 instead of libreoffice-gtk3 does cause issues with
the display of
some fonts in previously created documents. So, I'm not sure which is
worse. The
flickering or having to fix previous documents. Probably the flickering I
can live with
easier.
Yeah, I see this. If I move the pointer inside the icon, but still within
the icon's area, the flickering stops. After I stop, half a second later the
flickering comes back.
The flicking seems to be caused by repeated rendering of the pointer focus
border around the icon, and the icon's gradient background, when the pointer
is on top of it. Also, with no mouse movement, the mouse pointer itself
seems to occasionally jump about a dozen pixels diagonally, before snapping
back to its actual position.
Something is losing track of the mouse pointer and thinks it moved away,
draws the icon as if it's no longer under the pointer, then realizes that
no, the pointer is where it should be, so the icon should still be
highlighted.
top shows libreoffice's process eating 12% CPU, and X itself adds another
15% on top of it.
