I had the same problem on my laptop with an integrated Intel graphics 
card, I believe the issue started around the time of the 5.2 kernel 
There were a couple of threads on www.reddit.com/r/archlinux where 
people reported similar bugs.

Some of the tweaks mentioned in the wiki page on Intel graphics
appear to be relevant, but I was not able to fix the problem on Xorg, 
and after waiting for a few kernel and firefox updates I ended up 
switching browsers.

For the past month or so I've been trying Wayland out, I've been back on 
firefox since then and haven't experienced any graphics issues
