I just downloaded arena today on my dell, which runs on windows. I'm playing through the tutorial, but at a certain point in games cards will go to the stack and resolve there, so that they change to their on the battlefield look while in the stack side of the screen, and they will then stay there, but act as if they're on the battlefield, so enchantments will affect creatures, instants will buff, creatures will block and attack. There is a screenshot below of creatures attacking while they are displayed in the stack. This ultimately leads to some buggy blocker interactions, as it's hard to designate blockers with the touch and drag, and sometimes stops spells from resolving altogether, specifically one that was supposed to make tokens, but the tokens never appeared. The game functions fine, it's just as the user I can't always understand what's going on, as cards literally stack on top of each other, masking what is actually on the battlefield, and can't necessarily play the game because of that and other stated issues. I have already used the "repair game files" button present in the report a bug screen, and captured multiple game logs which are included below.
