@ monte:
Elanor has the project link to our app on Git Hub if you are interested. I
was going to submit a business support request to have your team examine that
stack and see if there was a way to optimze it but I think Jacque has the
bottom line:
the "Siva-Siva-Portal.livecode" stack is what Jacqueline is referring to. there
is a series of "link" panels or subgroups. each includes
"rows" with
414 wide grc about 100px high
Left site is a text field with the link "label"
right side is a small thumbnail.
These are then stacked on top of each other dynamically, based on a JSON file
that defines both the content of the row, what image is used etc.
It works rather well, surprising fast to build even on Android. BUT these are
all then grouped into one big group that is assigned the scrolling behavior…
AcceleratedRendering does help, because, we presume, the group is not a free
standalone group on top of the card.
ergo, until the Datagrid2 initiative is complete, apparently we have no
solution.
but you can try:
g...@github.com:Himalayan-Academy/Siva-Siva-App.git
be sure to check out the "nightly" branch… which is the most up-to-date… then
you boot Siva-Siva-App.livecode (launcher stack which is never close)
and after it init's (starts using all the libs) then it opens the
Siva-Siva-Portal.livecode stack
that’s the one that "jitters." when it scrolls, quite a few beta testers who
"are sensitive" have pointed this out… Others seem not to care, they are
focused on content/navigation and not necessarily screen performance… it's fast
enough, just "ugly scrolling"
The structure is
card "portal"
group "Portal Layout" # contains 2 groups
group "SivaSiva Portal Scrolling" # this is the group that scrolls
very badly no matter what we do.
# Sub groups
Header-group
row 1 -(small group)
row 2 -(small group)
row 3 -(small group)
row 4 -(small group)
row 5 -(small group)
group "SivaSiva Portal Navigation
# this a fixed tool bar at the bottom of the screen
Ahhh, I wonder if we only had two groups like this
card "portal"
group "SivaSiva Portal Scrolling" # this is the group that scrolls very
badly no matter what we do.
# Sub groups
Header-group
row 1 -(small group)
row 2 -(small group)
row 3 -(small group)
row 4 -(small group)
row 5 -(small group)
group "SivaSiva Portal Navigation
# this a fixed tool bar at the bottom of the screen
so that the group that scrolls is *not* inside another group… if accelerated
Rending make it scroll better.

@Mark: I've just found why it's failing. It's the stack structure, not
the engine. That's what happens when a lot of people work on the same
project; it changed without my noticing.
