sorry I didn't notice.
did they respond? I hope they will solve it
No response so far however i'm certain they are aware of it as I and a few others have mentioned it a few times (with videos) and it has been confirmed by several others (yourself included). It's also important to note that it occurs when a taskbar button has been removed by any means. This includes closing a top level window as well as moving the window to another monitor (the button is removed from the taskbar of the starting monitor and then added to the destination monitor).
While you wait there are 2 solutions I found that works. Neither are great but you can use them while we wait for a proper solution.
1. Use left aligned buttons. Sadly you give up center aligned buttons which I personally like.
2. Turn off the option for Start11 to "Enhance" the taskbar. In this case you can use windows taskbar settings to get center aligned buttons however since the new taskbar sizes buttons based on the text (if you have show labels on) you will end up with variable sized buttons.
Again neither solution is perfect however I'm current using option 2. While mismatched button sizing is a bit ugly (also windows does not update button text properly) i feel i can live with it for a minute.
Hope this helps
