I've only switched to the 2070 in the last month, previously I was running a 1060 with all the same problems (The "window stops working" bug has haunted me on and off for a year or so, but you may be right that the tab bar glitches could have gotten worse since switching to the 2070) I am on 418.56, I will look into upgrading.
