The text in the image is actually white and say "learn more" but for some reason, it displays like this, and even worse exports like this.

If I select the text, it looks like it should, but as soon as I deselect it, it reverts to the above corruption. (it varies in how corrupted it looks, sometimes it's the whole word, sometimes it's bright green etc) - I've switched off the graphics card in "performance" but it doesn't help.
