Ok, I think I have a fix. Deleting my Thunar config files helped. But here's the tricky part:You know the "~/.config/Thunar" directory? That apparently is not the Thunar config file location. Instead, I removed "~/.config/xfce4/xfconf/xfce-perchannel-xml/thunar*". After restarting Thunar, my Trash can worked correctly.
I have noticed a very high cpu usage from X (40-60%) when I scroll along on thunar's menus (File, Edit, View etc.).The above is getting worse when I have thunar window maximized.I am using Openbox as WM and I have nvidia graphics.I ran xrestop but I can't figure out anything abnormal.Any suggestions?
