All of the cells in my notebooks that have the option TextAlignment->Center are broken since updating to MM 13.1. It seems that the TextAlignment option does not update correctly as I change the window size. Is anyone else having this issue?

The only way I can get it to update correctly is to show the underlying code and then close it. The video below demonstrates the issue and the rather annoying workaround.

I am using the default stylesheet.

Update --- Other users have confirmed this as a bug. Note that TextAlignment fails in the Wolfram Documentation as well. See the 1st example of the "scope" section of TextAlignment in the documentation:

Do[Print[Style[a, TextAlignment -> a]], {a, -1, 1, .5}]

Window resizing does not auto-update the positions. A temporary fix is to show and close the underlying code.

    $\begingroup$ I can reproduce this with Input, Output, and DisplayFormula cells (and I'm also using 13.1). The other dozen or so cell formats I tested did auto-update on resize (didn't do exhaustive testing). $\endgroup$

    $\begingroup$ The 1st example in the "scope" section of TextAlignment documentation is good to verify that this is indeed an issue: Do[Print[Style[a, TextAlignment -> a]], {a, -1, 1, .5}] . I think this should have the bug tag $\endgroup$

I contacted Wolfram. They confirmed it is a bug. They forwarded the information to their developers. Hopefully, it's fixed sooner than later.

In the meantime... I put a button on my toolbar that temporarily fixes the issue in the current notebook until you resize the window again.

Button["Update", 
 Do[FrontEndExecute[
   FrontEndToken[InputNotebook[], "ToggleDynamicUpdating"]], {2}]]

I'm placing this button in all of my notebook toolbars but also my exported notebook toolbars for my students since they use the WolframPlayer. The player has the same issue.
