BUG: Delay in updating app indicator on closing/opening applications

[m44soroush]

Description:
The "Dash2Dock Lite" GNOME Shell extension provides a useful feature called "App Indicator," which displays the number of open windows for each application by placing dots under their respective icons on the panel. However, there is an issue with the current implementation that causes a delay in updating the indicator dots when closing or opening applications.

In certain scenarios, after closing or opening an application, it takes approximately 4 or 5 seconds for the indicator dots to update and reflect the correct number of open windows. Surprisingly, the dots instantly update when the mouse pointer is moved over the panel. This delay in updating the dots without any mouse interaction can be inconvenient and disrupts the smooth user experience of the extension.

This issue is reproducible consistently, and it affects the overall usability of the Dash2Dock Lite extension. Users would greatly benefit from a prompt update of the application indicator dots upon closing or opening applications without relying on mouse movement as a workaround.

Steps to Reproduce:

• Install and enable the Dash2Dock Lite extension on GNOME Shell.
• Open multiple applications that support the app indicator feature (e.g., Firefox, Files, Terminal).
• Observe the application indicator dots under their respective icons on the panel.
• Close or open one or more applications.
• Wait for approximately 4 or 5 seconds and note the delay in updating the indicator dots.
• Move the mouse pointer over the panel and observe that the dots instantly update.

Expected Behavior:
The application indicator dots should update promptly upon closing or opening applications, without requiring the user to move the mouse pointer over the panel.

Actual Behavior:
There is a noticeable delay of around 4 or 5 seconds before the application indicator dots update after closing or opening applications. The dots instantly update only when the mouse pointer is moved over the panel.

Environment:

GNOME Shell version: 44.2
Dash2Dock Lite extension version: 30
Operating System: Ubuntu 23.04

Additional Information:
Please let me know if there are any troubleshooting steps or logs that I can provide to assist in resolving this issue.

Notice the absence of dots initially, which take approximately 4-5 seconds to appear under the Terminator icon on the panel. Moving the mouse pointer over the panel triggers an instant update of the dots.

Hi @m44soroush , could you check if the same issue persists for you on Gnome 45.
Gnome 44 is currently way behind in the development.
