I noticed in Ubuntu 24.04 that when changing virtual desktop the GNOME windows ripple for active window does not respect the chosen accent color. While in Ubuntu 23.10 it did (see here). If this needs to be bug report please let me know thanks.
Please report a bug to gnome-shell by running:
ubuntu-bug gnome-shell
and include more details about what you mean by “ripple”.
This site has a different purpose than technical support. The Finding Help topic details where you can get support for Ubuntu.
Once you have the bug report opened, please keep the bug discussion there.
