Touch screens are slow to respond when selecting a channel after firmware update

Running a dLive S7000 connected to DM64 via 2x RJ45 lines. Just updated to the 2.12 firmware last week and have noticed a significant delay when pressing select on a channel to when it populates on the touchscreens. The delay appears to be specifically when going between channel banks as channel selection inside one bank is normal. However, when selecting a channel in a different bank there is ~5 seconds of delay before it appears on the touch screen. Audio is unaffected, seems to be a graphical issue only, but it is problematic.

Has anyone else noticed this?

Edit: I forgot to point out that I have another S7000 connected to a DM0 that is experiencing the exact same problem. Both updated at the same time.

I have noticed such delays when switching scenes. Was definitely not the case prior 2.10.
