I wanted to increase privacy on my home directory so I chmod -R 750 /home/Me/. After doing so my desktop fonts went from nice smooth font's to fonts with rough edges , panels with thick boarders and theme specific icons disappear to default ones.
My guess was that some program no longer had access to a needed file. So I played with a number of permission combinations and found that chmod -R 771 brought me back to normal.
The issue is that I don't want that on my data. (want 750) but when I chmod all but the data to 771 and data at 750 I have the issue.
The other strange thing is now the same issue is coming up intermittently without me changing permissions.
