After set new wallpaper with pcmanfm-qt, wallpaper will not update without trigger

[ghost]

Hi.
I use the dynamic wallpaper (xplanetFX), which use the external script to update wallpaper.
I decide to test updating wallpaper with terminal:
pcmanfm-qt --set-wallpaper=/home/user/picture.jpg --wallpaper-mode=fit

Expected Behavior

Wallpaper should update immediately.

Current Behavior

When cursor remain over any window region, wallpaper will not update.
Wallpaper will update after mouse cursor move over free (unoccupied with any window) desktop space.

Possible Solution

Steps to Reproduce (for bugs)

1. Use any terminal. Set the mouse cursor under any window region;
2. Use command: pcmanfm-qt --set-wallpaper=FILE --wallpaper-mode=MODE
3. Do not move the mouse cursor (wallpaper will not update)
4. Move the mouse cursor over free (unoccupied with any window) desktop space: wallpaper will update.

There was no need to close this. Do you want to open it at pcmanfm-qt?
