i too have seen purple bars replacing the bold text on my collection. when I’m making a custom mage deck, if I mouse over my cards in my deck, the bold text of all the cards on the collection page I’m on will turn to purple bars.

Very widely reported. Seems to be caused when a lot of cards views are generated quickly, e.g. mousing rapidly over a deck list. Appears to affect all onscreen cards, but not future ones.
