Public bug reported:

In kernel version 5.3 *, the touchpad does not work properly. On the login 
screen it works, but after logging in, only the left half of the touchpad 
works. Both click buttons work.
I know that I am on Linux Mint, but I am new to Linux and I do not know if I 
should resort to you, or if the bug also affects you, etc. I reported the bug 
to both OS.
Thanks for read.
