Ok... so here's an update...
The card that contains all this is a calendar. On this card is a header, a
datagrid that lists the events of the selected day, and another group with 84
controls in it (one button and field for each possible day) that makes up the
calendar's grid, and more. When you click "New Entry" or "Edit Entry", we
hide the calendar and show the group "newEventG" which, as you know, contains
several other groups for setting the event's properties (title, notes, dates,
repeat, and more). It is in the group "newEventG" that we are seeing all the
sluggish behavior.
Last night, I painstakingly moved group "newEventG" to its own card. Now, the
speed is no longer an issue. It's snappy and responsive. I have to wonder if
having a hidden group with so many controls was messing things up.
Mark, to answer your question, there isn't one image on the entire card.
ShowFocusBorder was on.
All these were correct:
- opaque must be false
- showName must be false
- hScrollbar must be false
- vScrollbar must be false
- showBorder must be false
- all bitmap effects must be empty
I am in a good place now and ok to continue with my project (although the
tablet version is now funky as it moves to another card for event editing
rather than the group overlay). I hope all this helps LC resolve whatever this
issue is.

So the first thing to do is (on Desktop) run with acceleratedRendering
and ensure that:
1) 'the effective layerMode of group "newEventG"' is container
2) 'the effective layerMode of group "ne_mainControls" is dynamic
3) 'the effective layerMode of group "ne_repeatG" is dynamic
If (1) does not turn out to be the case then acceleratedRendering will
have a slightly negative effect (as the engine will be doing what it
would do without acceleratedRendering on, but also paying the overhead
of caching the result!). To fix this you'll need to tweak the properties
of the newEventG group:
- opaque must be false
- showName must be false
- hScrollbar must be false
- vScrollbar must be false
- showBorder must be false
- all bitmap effects must be empty
Essentially the rule here is that for a group to be a container layer it
must not have to render anything itself (as it is just meant to
'contain' other layers).
If you get the groups effective layerModes as above I'd imagine you
*might* see a slight increase in performance with acceleratedRendering
on - the showing and hiding of the dynamic layers is essentially 'free'
in this scenario - but their content does need to be cached first.
Caching of dynamic layers happens incrementally as parts of them are
visible.
However, given the difference in speed between the platforms with
acceleratedRendering off I'm inclined to think something else is going
on here... The CPU on a Moto G5 Plus is substantially less powerful than
even an iPhone6S - but definitely not 50x!
You mentioned in another thread that you were using custom fonts... Do
you get better performance if you remove the use of custom fonts and
just go with the default?
Warmest Regards,
Mark.
