If you haven't updated to linux 5.2 yet, you should because it fixed constant
flickering when in LFC mode.

This additional patch helps when the monitor goes in and out of LFC mode. It's
not fully fixed, but the flickering is a lot less severe. According to the
Phoronix article it should indeed land in linux 5.5.

When compiling a kernel you should be able to install it next to the regular
one so you can't break your setup. I personally used the linux-mainline package
from AUR and added the LFC patch on top.
