Grid and ViewBox layout issue with latest version 12.1.3 - Regression ?

[LaurentInSeattle]

With this latest version, all viewbox'es that have inside grids are laid-out at zero size. Whatever i had placed in the viewbox, paths, or icons etc
I had no time today to fully investigate and create a repro project and wont be able to create one in the next few days, therefore I reverted to 12.1.2 and everything is "back in business"...

Regression? Am I the only one to see this ?

Thanks!

Sounds like a regression but need somehow a sample.

Best if we can turn it into a unit test.

#22284

Maybe this i PR also would fix this issue. Worth to try once there is a package available.

[LaurentInSeattle]

Provided a sample... Really looks like a regression.

Made a repro app: Problem is related to Path present in a viewbox:

Screenshot for Ava 12.1.2 Curves are "there"

Upgrade to 12.1.3, and they are "gone" - Flag in Viewbox still works

Test App:

AvaBug.zip

That's just AI slop, not an answer.

[timunie]

@Matubil if you are a person and really want to help, make a failing unit test out of the failing sample and then provide a fix. One can use AI for some assistance but we don't need anyone just forwarding the AI outcome.

Looks like this PR #22213 is the one in 12.1.13 that 'deals' with Paths.

Could it be the 'culprit' ?

@timunie This is visible in ControlCatalog with latest main branch as of today. Go to the ColorPicker page and the ColorView tabs have blank tab headers. There should be icons there. They use PathIcon which internally uses a ViewBox.

#22213 is the culprit. Reverting in #22294.

So.. Are we going to get a 12.1.4 soon ?
