Can you move cursor during these periods?

Yes, no issues with the cursor (mouse pointer).

I would still try to disable typing detection to test if it affects behavior of buttons.

But this is something in /var/log/lightdm/x-0.log:

(EE) event14 - VEN_04F3:00 04F3:311C Touchpad: kernel bug: Touch jump detected and discarded.
See https://wayland.freedesktop.org/libinput/doc/1.22.1/touchpad-jumping-cursors.html for details

Do these entries correlate with issues with buttons?

After reading of the linked page I suspect that the touchpad may misinterpret button clicks as cursor jumps.
