Top 3 lines of lcd are blanked with 2.3.57.4

[neophyl]

Sliced some gcode with the new 2.3.57.4 release and when printing using it on my Prusa MK3 the lcd details are now missing except for the bottom line. So basically all the temperature, speeds etc that are normally displayed are blanked out.
I haven't changed anything in my printer profile, its still set to use the M117 for print time remaining etc.

The printers lcd works normally in that if I go into the menu to change something it displays everything as expected but once I go back to the main screen the only line being shown is the very bottom line with the scrolling name of the print job.

Slicing the same project from 2.3.57.3 or 2.3.26.9 and printing results in lcd normal operation.
I've compared the gcode produced and the only thing I can see different (besides some of the move/extrude values) are the M73 lines. The latest one is missing the Q values and repeating the first line.

Why this should result in a cleared lcd though I have no idea.

Expected behavior
Not to clear the lcd screen of all the other information

That's the silent mode. I didn't see it need different parameters.
Should be an easy fix.
