Task dialog flickers/blacks out when opening completed or deleted tasks

[ShivaGupta-14]

Describe the bug
When opening a task dialog for a task with status "completed" or "deleted", the dialog content starts flickering rapidly. If the cursor is moved over the dialog, the dialog screen goes completely black and becomes unresponsive.

To Reproduce
Steps to reproduce the behavior:

1. Go to http://localhost:5173/home
2. Make sure you have multiple completed or deleted tasks in your task list
3. Click on any task with status "completed" or "deleted" to open its dialog
4. Dialog content starts flickering
5. Move cursor over the dialog
6. Screen goes black and becomes unresponsive

Expected behavior
The task dialog should open smoothly and display task details without flickering, regardless of task status (pending, completed, or deleted).
