I recently upgraded a customer from V7.9 to V8.1. Before the upgrade, when I click on an object on the screen, you would get the dashed box around it while it was writing the tag to the PLC. Now w/ V8.1, it doesn't do that anymore. Any ideas why? TIA.

You might want to tag the question as "Vision" to attract the relevant audience.
Is it a binding? If so, the dashed rectangle won't appear if 'Overlay Opt Out' is checked:
Yes. Tag is getting written. I do not have that checked.
Check if the tag group involved has "Optimistic Writes" turned on.
What type of component is it? On my test system, I am running version 8.1.26, and on checkboxes at least, I still get the overlay.
It's turned off
Hmmm; with opt-out not selected, the overlay should be there. If nobody else has an idea, I imagine support will want to take a look at it to see what got messed up during the update.
I put a simple toggle button on the screen and that worked fine... The hunt continues.
A custom graphic with touch scripting.
Hmmm. I thought the write overlay was only intended to work on input components. Maybe this was a "bug" that got fixed?
I have an educated guess as to the problem.
In 8.0 we switched to a new QualityCode interface, but Vision has to keep using the legacy data qualities. So there's some bridging logic to allow both property types to be used for bindings, but it's currently broken. So the write_pending quality is probably not getting broadcast from the inner binding out to the template.
OP, this is an extension of an existing bug - you should contact support so we can prioritize it higher and let you know once it's fixed.
