Unable to pull focus from desktop application without mouse intervention

[1a2s3d4f1]

Description

When running a desktop application(e.g. xfdesktop or pcmanfm-qt --desktop) from terminal, the focus be stuck in desktop application even opening a new window, the window is not focused so i can not control it by keyboard. I found the cursor was stuck by desktop application, it means that the desktop application catch the inputs via keyboard. In addition, the window can be focused but the desktop application can't be focused while follow_mouse=3 is set.

How to reproduce

1.Start Hyprland session and launch a terminal kitty with keybinds
2.Run xfdesktop in kitty and switch to another clearly workspace with keybinds
3.Launch an application via keybinds
4.Note the application doesn't have focus,but you can press button f5 to refresh desktop if using xfdesktop.
5.click mouse or move mouse if follow mouse enabled
5.Launching additional applications work as expected once a window has focus
7.Closing all application and launch a app exhibit the symptoms again
