Loot tooltips?
 

Maybe I'm losing my mind but I could have sworn that there were mouseover tooltips for loot items. That said, I made a new character recently and I am not seeing them. I have to right click + hold to see what is on a corpse I'm looting. Did I accidentally disable them somehow?

Corrupted temporary files are believed to cause this problem. Restarting your computer should fix this issue.

That did fix it, thanks
