windows all shift 3-4 pixels left every workspace change in F42

I just upgraded to Fedora 42 (from F41).  A new bug appeared that causes
all windows on the screen to shift 3-4 pixels to the left every time I
change workspaces.  The more I change, the more they shift!

It seems to me the shift is by the same width as the border window
decoration.  Maybe that's related, maybe it's a red herring.

What is causing this?  Is there a quick workaround I can do?  I can help
debug potential fixes, even if it needs a recompile.

The version in F42 is currently 1.13.0

Thanks!
