Post From: 2875 Lag flipping chartbooks

Been using Sierra for over 3 years now. I say that because I'm familiar with the speed and performance of Sierra.
Tonight, when I returned to my computer, my data feed was down. I tried restarting Sierra was prompted to update- so I did. Currently 2875.
I'm seeing a very noticeable lag when flipping my chartbooks.
I flip a lot of chartbooks throughout the day. Previous versions of Sierra have always been amazing, and Sierra was always super responsive when flipping chartbooks. But I downloaded the pre-release update some weeks ago and noticed some lag compared to the older versions. But tonight, when I downloaded the new update, flipping chartbooks is painfully slow compared to the responsiveness I've experienced previously. Nothing has changed on my end, normal CPU usage and chartbooks are unchanged.
Some graphical things unique to the update I see associated with the lag I'm experiencing include=
1) I have a chart trade window attached to one chart per chartbook. In this latest update, when I flip chartbook- the chart trade window is temporarily invisible before rendering. Feels associated with the lag somehow.
2) Charts that are not minimized but underneath another overlapping chart will flash before the top chart renders when flipping to a different chartbook.
3) If I hit flipchart (hot key) multiple times to cycle to a specific chartbook, the lag somewhat compounds and the flipping does not match the speed I hit the hotkey. Previous versions were much more responsive worked great.

Thank you for all you do.
