I'm still seeing the problem after the update.  This is with:

In GNU Emacs 29.0.50 (build 39, x86_64-pc-linux-gnu, GTK+ Version
 3.24.33, cairo version 1.16.0) of 2022-09-03 built on joga
Repository revision: 91ba20fff159cc88c87e09f5a8256d6412c98990
Repository branch: master
Windowing system distributor 'The X.Org Foundation', version 11.0.12101003
System Description: Ubuntu 22.04.1 LTS

Configured using:
 'configure -C'

Configured features:
ACL CAIRO DBUS FREETYPE GIF GLIB GMP GNUTLS GPM GSETTINGS HARFBUZZ JPEG
JSON LCMS2 LIBOTF LIBSELINUX LIBSYSTEMD LIBXML2 M17N_FLT MODULES NOTIFY
INOTIFY PDUMPER PNG RSVG SECCOMP SOUND THREADS TIFF TOOLKIT_SCROLL_BARS
WEBP X11 XDBE XIM XINPUT2 XPM GTK3 ZLIB

And I now have a semi-reliable way to reproduce it.

emacs -Q
C-x 5 2

Then start another Emacs, and place that frame over frame 2.  Then give
frame 2 focus.  Then switch to the other Emacs (which is covering frame
2).  Then click on the title bar of frame 1.  Both frame 1 and the other
Emacs then have blinking cursors.

This is with Gnome Shell.
