[Linux] XFCE - Missing Window Border and System Button

This problem happen to me in last 2 days. When I login with xcfe desktop, I always found my window had no border and no minimize, maximize, and close button. I try to search this problem, and found the solution. Delete all files in this folder, and try to login again.

/home/youraccount/.cache/sessions/

*the folder .cache is hidden. Check the Show Hidden Filesinside View Menu.
