I seem to notice that when a reward pops up after a match when you complete a quest, the screen goes blurry (usually mostly with card pack awards)
All the buttons still work, like the Shop, back button etc and usually if you open a pack (I don’t think I’ve tried by opening the collection) and check your new cards, it usually rights itself.
I believe I’m playing on the right resolution for my laptop.
EDIT: “This is an issue that is listed on our Known Issues list. Let’s focus on the primary thread for reports to keep this linear, locking this thread.”
I apologize, I didn’t see it.
