[2021] [PC] Click-drag-click bug?

I normally play MtGA by clicking on the card I want to play, dragging it to the battlefield, and clicking again. To clarify, this is not drag and drop, it's click-release-drag-click. That's just how I'm used to play the game.

Thing is, since last update (a few hours ago), it's become extremely wonky. It typically takes me 4 or 5 attemps to play a card. I haven't noticed any particular reason why (cards beneath the cursor, battlefield area, whatever), it's just fickle. The problem persists between matches and restarting the client doesn't seem to have any effect.

Anyone knows what could cause this? Drag and drop and double click work fine, so the game isn't unplayable, but that's still mighty annoying.
