[GAMEPLAY] Screenshots i take in game doesnt look the way they are supposed to

So, i noticed that my screenshots started to look really strange. Most of the time when i make a Quadra or a Pentakill i tend to take a quick screenshot of it and send it to my friends to show them that i did something cool.(And they do this too). And in the past few weeks my screenshots have started to look like the examples i have included: The multikill titles and the name tags are colored black and the chat sometimes also looks a bit strange. And i think the overall quality of the screenshots is worse. (And strangly, if you try to zoom in on the picture in imgur everything brightens up and the title and the names become white.) One of my friends is also experiencing this and i would really apprciate a fix for this.
