I'm guessing I must have a setting wrong as otherwise this would be a major bug. I play STTs, and have recently started using a game pad to play, rather than a mouse, so this issue has only recently become apparent to me. The problem is that the table to act "switches" sometimes just as I'm about to act, meaning that I may make the wrong action on the table it switches to. Sometimes it flicks momentarily to the new table and flicks back, other times it stays on the other table. Obviously with a mouse this doesn't matter because I'd still be clicking on the right table (I play tiled), but with a game pad I'm making the wrong action.
It often seems to happen when a new table has opened, or when a new table requires me to act for the first time.
I did wonder whether it was just me imagining it or not concentrating, but, without a doubt, this has been happening, and it's becoming tilt-worthy, I called an all-in with something like 52o earlier.
I play with 12 tables tiled but overlapping, not sure if this is relevant.
