I believe MTG Arena Beta has ruined my SurfaceBook 2. Whatever happened in the last update has made Arena unplayable on my PC and has spread issues throughout my computer. I no longer have control of my pointer, it runs to the bottom and randomly starts clicking at the bottom of the screen. Almost like a virus, except the issue started in Arena while playing. I have reformatted, used several anti-virus software only for my computer to come back squeaky clean. Diagnostics also says there is nothing wrong with my Surface book yet I can't control my mouse and some of the touch functions are messed up. It might be b/c my surfacebook is a tablet as well and Arena isn't compatible with tablets, but seriously, for a free game to kill my $4k dollar computer.... that's a bit ridiculous.
