Did you change anything recently? Are all your Drivers updated?

There is a setting that makes everything look like that with no animations to improve performance.

Follow that guide and check if that's what has changed. There are checkboxes that say "adjust for best performance". Probably that changed.

If it just randomly changed like that run an Anti-virus. Thats what happened to my parents old PC, that ended up having bad malware that fried it
