you on windows or linux? you could probably fix this on linux with a desktop compositor like compton which i use but for windows youre probably shit outta luck.
you can use borderless windowed fullscreen or borderless windowed in general, if you want to not have screen tearing. thats what worked for me, on windows at least.
edit: from what ive heard from friends u can buy a freesync/gsync monitor and that should fix it?? idk
