This is the problem when other threads are not brilliantly written and you have to read between the lines... I get used to "filtering out" the word "manjaro" in thread titles as every other issue mentions it... ("$APPLICATION won't run on Manjaro", to which I think, Why mention Manjaro given you're posting on the Manjaro forum?).
Something is off with your drivers or graphics stack. Let's start over, with an
inxi -Fxxxz just so we can see what we're dealing with, and double-check there are no updates/changes with
sudo pacman-mirrors -f3
sudo pacman -Syyu
Also post output if that mentions any newer packages.
