[3.5.2] DWC has some bad noticeable display lag

[PDBeal]

Very noticeable display lag on 3.5.2 on DWC when using Duet + SBC + PanelDue. Watching the temperatures rise/fall appears to be frozen, then quickly counts, then holds, then quickly counts again. Even watching the X, Y, Z, U positions also has this delayed display.

Functionally, it works, but it was not like this prior to 3.5.2.
