Dialog text gone @Windowed fullscreen (ultra wide monitor)

Playing the campain in Windowed Fullscreen with an ultra wide monitor (2560x1440@100). The screen is of Predator brand.

Expected result:
When cutsceens have dialog, I’d expect subtitle to the right of the portrait that indicates who’re talking, also their name.
Like so:

Arthas Menethil:
“It’s good to see you Jaina.”

Actual result:
I see a portrait but no name nor subttitle.

Quite sad because it removes names. Sometimes I’m not sure who the character is that’s talking.

This does not happen when only Windowed or only Fullscreen. I don’t see any black bars to the right and left (which is great!) in Windowed fullscreen.

Happy bug fixing!
